TL074 LINEAR INTEGRATED CIRCUIT
LOW NOISE QUAD J-FET
OPERATIONAL AMPLIFIER
DESCRIPTION
The Contek TL074 is a high speed J- FET input quad
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.

TL074 LINEAR INTEGRATED CIRCUIT
SCHEMATIC DIAGRAM
ABSOLUTE MAXIMUM RATINGS
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 Toper 0 to 70
Storage Temperature Tstg 5 to 150
NOTES: 1. All voltage values, except differential voltage, are with 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-i nverting 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.
