OPA604AU

Texas Instruments · FET Input Amplifiers · SOIC-8

OPA604AU 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 null pin used with a trim potentiometer (50kΩ to 1MΩ, 100kΩ recommended) for about ±50mV typical trim range; may be left unconnected.
2 -In input Inverting input; input voltage must stay within (V-)-1V to (V+)+1V, with typical common-mode range of ±13V at VS=±15V.
3 +In input Non-inverting input; input voltage must stay within (V-)-1V to (V+)+1V, with typical common-mode range of ±13V at VS=±15V.
4 -VS power_in Negative supply; operating voltage range is ±4.5V to ±24V total supply with absolute maximum ±25V, and a 1µF tantalum capacitor at the pin is usually adequate for decoupling.
5 Offset Trim passive Offset null pin used with a trim potentiometer (50kΩ to 1MΩ, 100kΩ recommended) for about ±50mV typical trim range; may be left unconnected.
6 Output output Op amp output that drives a 600Ω load to typically ±11V to ±12V, with short-circuit current of about ±40mA and continuous short circuit to ground allowed.
7 +VS power_in Positive supply; operating voltage range is ±4.5V to ±24V total supply with absolute maximum ±25V, and a 1µF tantalum capacitor at the pin is usually adequate for decoupling.
8 NC unconnected No internal connection.
