OPA37GU

Texas Instruments · Operational Amplifier · SOIC-8

OPA37GU from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Offset Trim passive Offset voltage trim pin. Connect to pin 8 through a 10kΩ potentiometer (1kΩ to 1MΩ range) with wiper to +VCC for ±4mV typical offset null. Leave open if trim is not required.
2 -In input Inverting input of the op-amp. Common-mode input range ±11V (±12.3V typ) at ±15V supplies. Input bias current ±15nA typ, protected by back-to-back diodes (limit differential input current to ±25mA if VDIFF exceeds ±0.7V).
3 +In input Non-inverting input of the op-amp. Common-mode input range ±11V (±12.3V typ) at ±15V supplies. Input bias current ±15nA typ, protected by back-to-back diodes.
4 -VCC power_in Negative supply rail. Rated ±15V, operating range ±4V to ±22V (absolute max ±22V). Quiescent current 3.3mA typ (5.7mA max) at IO = 0mA.
5 NC unconnected No internal connection. May be left floating or tied to a DC potential; no functional effect on the amplifier.
6 Output output Amplifier output. Voltage swing ±12V min (±13.8V typ) into RL ≥ 2kΩ; short-circuit protected with 25mA (60mA max) short-circuit current. Open-loop output resistance 70Ω.
7 +VCC power_in Positive supply rail. Rated ±15V, operating range ±4V to ±22V (absolute max ±22V). Bypass with a local decoupling capacitor to ground.
8 Offset Trim passive Offset voltage trim pin. Connect to pin 1 through a 10kΩ potentiometer with wiper to +VCC. Nulling large system offsets via this pin degrades drift by ~3.3µV/°C per mV of trim.
