TL072 LINEAR INTEGRATED CIRCUIT
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 v
voltage range
*Low input bias and offset current
*Low noise e
*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)

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 Vccand 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.
