LOW NOISE DUAL J-FET
OPERATIONAL AMPLIFIER
DESCRIPTION
The ContekTL072 is a high speed J- FET input dual
operational amplifier. It incorporates well matched ,
high voltage J- FET and bipolar transistors in a
monolithic integrated circuit. The device features high
slew rates, low input bias and offset current, and low
offset voltage temperature coefficient.
FEATURES
*Low power consumption
*Wide common-mode (up to vcc+) and differential
voltage range
*Low input bias and offset current
*Low noise en= 15nV / Hz(typ)
*Output short-circuit protection
*High input impedance J-FET input stage
*Low harmonic distortion:0.01%(typ)
*Internal frequency compensation
*Latch up free operation
*High slewrate:16V/ms(typ)

BLOCK DIAGRAM
ABSOLUTE MAXIMUM RATINGS(Ta=25 C )
PARAMETER SYMBOL VALUE UNIT
Supply Voltage (note 1) Vcc +-18 V
Input Voltage (note 2) Vi +-15 V
Differential Input Voltage (note 3) Vid +-30 V
Power Dissipation Ptot 680 mW
Output Short-Circuit Duration (Note 4) Infinite
Operating Free Air Temperature Range Toper 0 to 70 C
Storage Temperature Range Tstg -65 to 150 C
NOTES: 1. All voltage values, except differential voltage, are wi th respect to the zero reference level
(ground) of the supply voltages where the zero reference level is the midpoint between Vcc-
and Vcc+.
2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or
15 volts, whichever is less.
3. Differential voltages are at the non-inverting input terminal with respect to the inverting input
terminal.
4. The output may be shorted to ground or to either supply. Temperature and/or supply voltages
must be limited to ensure that the dissipation rating is not exceeded.
