MAX4246AKA+T - Maxim Integrated

General Description

The MAX4245/MAX4246/MAX4247 family of low-cost op

amps offer rail-to-rail inputs and outputs, draw only 320µA

of quiescent current, and operate from a single +2.5V

to +5.5V supply. For additional power conservation, the

MAX4245/MAX4247 offer a low-power shutdown mode

that reduces supply current to 50nA, and puts the ampli-

fiers outputs in a high-impedance state. These devices

are unity-gain stable with a 1MHz gain-bandwidth prod

uct driving capacitive loads up to 470pF.

The MAX4245/MAX4246/MAX4247 family is specified

from -40°C to +125°C, making them suitable for use in

a variety of harsh environments. The MAX4245 single

amplifier is available in ultra-small 6-pin SC70 and space-

saving 6-pin SOT23 packages. The MAX4246 dual

amplifier is available in 8-pin SOT23, SO, and µMAX®

packages. The MAX4247 dual amplifier comes in a tiny

10-pin µMAX package.

Detailed Description

Rail-to-Rail Input Stage

The MAX4245/MAX4246/MAX4247 have rail-to-rail input

and output stages that are specifically designed for low-

voltage, single-supply operation. The input stage consists

of composite NPN and PNP differential stages, which

operate together to provide a common-mode range

extending to both supply rails. The crossover region

of these two pairs occurs halfway between VDD and

VSS. The input offset voltage is typically ±400µV. Low-

operating supply voltage, low supply current and rail-to-

rail outputs make this family of operational amplifiers an

excellent choice for precision or general-purpose, low-

voltage, battery-powered systems.

Since the input stage consists of NPN and PNP pairs, the

input bias current changes polarity as the common-mode

voltage passes through the crossover region. Match the

effective impedance seen by each input to reduce the

offset error caused by input bias currents flowing through

external source impedance (Figures 1a and 1b).

The combination of high-source impedance plus input

capacitance (amplifier input capacitance plus stray capac-

itance) creates a parasitic pole that can produce an

underdamped signal response. Reducing input capaci-

tance or placing a small capacitor across the feedback

resistor improves response in this case.

The MAX4245/MAX4246/MAX4247 family’s inputs are

protected from large differential input voltages by internal

5.3kΩ series resistors and back-to-back triple-diode stacks

across the inputs (Figure 2). For differential-input voltages

Pin Description

much less than 2.1V (triple-diode drop), input resistance is

typically 4MΩ. For differential voltages greater than 2.1V,

input resistance is around 10.6kΩ, and the input bias cur-

rent can be approximated by the following equation:

IB = (VDIFF - 2.1V)/10.6kΩ

In the region where the differential input voltage approach-

es 2.1V, the input resistance decreases exponentially

from 4MΩ to 10.6kΩ as the diodes begin to conduct. It fol-

lows that the bias current increases with the same curve.

In unity-gain configuration, high slew-rate input signals

may capacitively couple to the output through the triple-

diode stacks.

Rail-to-Rail Output Stage

The MAX4245/MAX4246/MAX4247 can drive a 2kΩ load

and still typically swing within 35mV of the supply rails.

Figure 3 shows the output voltage swing of the MAX4245

configured with AV = -1V/V.

Applications Information

Power-Supply Considerations

The MAX4245/MAX4246/MAX4247 operate from a single

+2.5V to +5.5V supply (or dual ±1.25V to ±2.75V sup-

plies) and consume only 320µA of supply current per

amplifier. A 90dB power-supply rejection ratio allows the

amplifiers to be powered directly off a decaying battery

voltage, simplifying design and extending battery life.

Power-Up

The MAX4245/MAX4246/MAX4247 output typically set-

tles within 4µs after power-up. Figure 4 shows the output

voltage on power-up and power-down.

Shutdown Mode

The MAX4245/MAX4247 feature a low-power shutdown

mode. When SHDN_ is pulled low, the supply current

drops to 50nA per amplifier, the amplifier is disabled, and

the output enters a high-impedance state. Pulling SHDN_

high enables the amplifier. Figure 5 shows the MAX4245/

MAX4247’s shutdown waveform.

Due to the output leakage currents of three-state devices

and the small internal pullup current for SHDN_, do not

leave SHDN_ open/high-impedance. Leaving SHDN_

open may result in indeterminate logic levels, and could

adversely affect op amp operation. The logic threshold for

SHDN_ is referred to VSS. When using dual supplies, pull

SHDN_ to VSS, not GND, to shut down the op amp.

Driving Capacitive Loads

The MAX4245/MAX4246/MAX4247 are unity-gain stable

for loads up to 470pF. Applications that require greater

capacitive drive capability should use an isolation resistor

between the output and the capacitive load (Figures 6a, 6b,

6c). Note that this alternative results in a loss of gain accu-

racy because RISO forms a voltage divider with the RLOAD.

Power-Supply Bypassing and Layout

The MAX4245/MAX4246/MAX4247 family operates from

either a single +2.5V to +5.5V supply or dual ±1.25V to

±2.75V supplies. For single-supply operation, bypass the

power supply with a 100nF capacitor to VSS (in this case

GND). For dual-supply operation, both the VDD and the

VSS supplies should be bypassed to ground with separate

100nF capacitors.

Good PC board layout techniques optimize performance

by decreasing the amount of stray capacitance at the op

amp?s inputs and output. To decrease stray capacitance,

minimize trace lengths and widths by placing external

components as close to the device as possible. Use

surface-mount components when possible.
