High Dynamic Range 14-Bit, 65MHz A/D Converter
The ADS852 represents a major paradigm shift in product performance for
demanding communications, and test instrumentation applications. Giving
100dB of spurious free dynamic range and 75dB signal-to-noise ratio,
ADS852 includes a wideband 1GHz track/hold that provides excellent
spurious performance up to and beyond Nyquist. The low 0.25ps jitter
of the track/hold also leads to excellent SNR performance. The ADS852
can accommodate full-scale input ranges of 2Vp-p, 3Vp-p or 4Vp-p.
The ADS852 also offers flexible clocking, accepting either a low level
differential sine or square wave signal down to 0.5Vp-p. It is available in a
64-lead LQFP package.
A perfect pairing with the ADS852 is the ultra low noise, voltage feedback
OPA687 op amp. The OPA687 operates from a dual (±5V) power supply, offers a high SFDR and an output swing of ±3.5V making it an ideal
driver for the ADS852 in high performance communications applications. The OPA687 combines a very high gain bandwidth product of 3.2GHz
and large signal performance with an ultra-low input voltage noise of only 0.95nV/ Hz, while dissipating only 18mA supply current, making it an
ideal amplifier for high performance transimpedance applications as well. The OPA687 is available in SO-8 and SOT23-6 packages.
Current Feedback Op Amp Family w/Disable
The OPA681 (single), OPA2681 (dual) and OPA3681 (triple) are
high slew rate, high output power, unity gain stable op amps
with an optional disable feature. The disable feature is
particularly useful for power savings or implementing simple
multiplexing circuits. All three models offer dual (±5V) or single
(+5V) supply operation, high slew rate of 2100V/µs, and low
input voltage noise. The current feedback design makes
the OPA681 family members a perfect choice where gain
adjustment or higher gains are required.

Low Cost, Very Small 8-Bit, 60-80MHz ADCs
The 8-bit, 60MHz ADS830 and the 8-bit, 80MHz ADS831 are
high performance pipeline A/D converters with flexible options,
allowing their use in a number of applications. They provide an
internal or external reference option, accept either single-ended
or differential analog input, and offer a programmable input
range of 1Vp-p or 2Vp-p. The combination of near ideal SNR of
49dB, low DNL of ±0.35LSB and low power dissipation provide
the extra margin needed for demanding video, imaging and
communications applications. The ADS830 and ADS831 are
pin-for-pin compatible and are available in the narrow 20-lead
SSOP package.

DSL Line Driver/Receiver Application
This application circuit supports DSL applications at the CP
(Customer Premises) requiring 10 to 13dBm (crest factor of
5.33 for DMT) on a single +12V supply. The OPA2681 has the
right combination of output swing, output current and slew rate
at high gains to achieve low distortion at the required power
levels. The OPA2680 makes an excellent receiver amplifier
because of its low noise, high bandwidth and slew rate
performance margins. Where +12V or ±5V supplies are
available, and/or lower turns ratios are desired, use the
OPA2681/OPA2680.

Baseband Sampling
Burr-Brown offers several op amp and ADC combinations
for baseband sampling. An example of these parts are the ADS803
and the OPA642. The ADS803 gives 80dB of SFDR at 1MHz
and the OPA642 gives in excess of 90dB while having a low voltage
noise of 2.2nV/ Hz, making it compatible with the low noise
of the ADS803.
See Figure 8.
Wideband IF Sampling
Burr-Brown provides a variety of compatible wideband operational
amplifiers and ADCs with the necessary bandwidth and dynamic
range for IF sampling. The OPA687 gives in excess of 95dB SFDR at
20MHz and the ADS852 gives in excess of 100dB SFDR. Using this
ADC for undersampling at the 1st IF stage is also achievable due
to the wideband track/hold performance. For instance, the ADS852
track/hold offers a 1GHz bandwidth and a low 0.25ps jitter.
See Figure 7.

The 8-bit 60MHz ADS830 and the 8-bit 80MHz ADS831 offer
outstanding differential non-linearity performance with a
typical error of only 0.2 LSBs and 7.9 effective bits, making
them attractive for RGB to LCD conversion in both VGA and
SVGA systems. Along with the triple channel OPA3681, these
converters provide a winning combination.

Video Analog-to-Digital Conversion Systems
Burr-Brown offers a complete, A/D solution for video.
These A/Ds operate on a single +5V supply at low power, come
in SSOP packages, and the driver op amps are small and lowest
in cost. These op amps provide low distortion and highest video
signal to noise.
See Figure 14.
Our A/D converters for video range from 8-bit, 30MHz to 14-bit,
65MHz. See
SpeedPLUS
A/D converters for selections. The SNR
numbers in the selection table can be adjusted by 9dB for video
applications. Burr-Brown also offers a wide variety of video
drivers as shown in
SpeedPLUS
op amps.
3-Input CCD/CIS Signal Processor with A/D
VSP3000 provides a complete, three-input imaging signal for
CCD or CIS sensors. In CCD mode, it provides line (row) input
clamps and correlated double samplers for data and reference
timed to the CCD signal. In CIS mode, an input reference and
correlated single samplers sample data timed to the CIS signal.
Gain range is 0 to 13dB, linear in dB. The A/D’s high resolution
allows black level and gain control from DSP. Reference can be
internal or external. Programming can be parallel and/or
serial. The single A/D design uses only 350mW (CDS mode)
and comes in a small, 48-lead LQFP.
See Figure 13.

CCD Video Signal Processors
Burr-Brown offers a complete line of imaging signal processors
for video and still cameras with line (row) rate clamps, and
correlated double samplers for data and reference timed to the
CCD signal. Each provides a 0 to +34dB remote gain amplifier,
linear in dB, and black level controls for the CDS and inputs.
All are complete solutions with internal references.

Optic Receiver Amplifier
Burr-Brown offers you outstanding solutions for the
transimpedance amplifier portion of photodiode. The OPA655
is a FET-input op amp with 240MHz gain bandwidth product
and very low input noise (6nV/ Hz). It also features very fast
overdrive recovery (20ns). Applications limited by the op amp’ s
voltage noise will benefit from the OPA686’s voltage noise of
1.3nV/ Hz. The OPA689 has a guaranteed overdrive recovery
time of 2.8ns for those applications that require minimal signal
drop-out time.
See Figure 17.
Wideband Integrator
This circuit acts as an integrator that maintains better than 2º
phase accuracy over ≥5 decades of frequency. This compares
very favorably with the standard single op amp integrator using
the OPA680, which is accurate over ≥1.5 decades of frequency.
Also, this circuit maintains this accuracy at higher frequencies
(0.5 decades higher). The voltage divider ratio set by the 150Ω
and 75.Ωresistors keeps the composite amplifier stable, and the
phase errors low.
See Figure 18.

Many of your analog and mixed-signal applications circuits will benefit from the flexibility of Burr-Brown's high speed products.
The following circuits illustrate just a few of the diverse applications made possible with the expanding
SpeedPLUS
product line.
Composite Amplifier
This circuit is for applications that require a high speed op amp,
but need excellent DC precision. The OPA686 provides the high
speed functionality, while the OPA27 gives excellent DC
precision and low 1/f noise. The OPA130 is an optional
integrator that blocks the DC input (below 0.2Hz), leaving <1mV
output offset voltage. This circuit could be used as a LNA (Low
Noise Amplifier), or as a driver for a diode mixer.
