OPA602AU

Texas Instruments · Precision OpAmps · SOIC-8

OPA602AU from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Offset Trim passive Offset voltage trim terminal; a 10kΩ to 1MΩ trim potentiometer (100kΩ recommended) gives a ±10mV typical trim range.
2 -In input Inverting input; the datasheet says to keep wiring short and avoid stray capacitance here, and input bias current is ±1pA max.
3 +In input Noninverting input; the datasheet says to keep wiring short and guard the board against leakage, since leakage can exceed the ±1pA max input bias current.
4 -VS power_in Negative supply; rated ±15VDC, derated performance from ±5V to ±18V, with absolute maximum supply of ±18VDC.
5 Offset Trim passive Offset voltage trim terminal; a 10kΩ to 1MΩ trim potentiometer (100kΩ recommended) gives a ±10mV typical trim range.
6 Output output Amplifier output; the op amp is unity-gain stable and easily drives capacitive loads up to 1500pF.
7 +VS power_in Positive supply; rated ±15VDC, derated performance from ±5V to ±18V, with absolute maximum supply of ±18VDC.
8 NC unconnected No connection, as marked NC on the SO-8 pin configuration.
