OPA2237EA

Texas Instruments · Precision OpAmps · VSSOP-8

OPA2237EA from Texas Instruments, in a VSSOP-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 OUT A output Channel A output; voltage swing from (V-)+0.001V to (V+)-0.75V.
2 -IN A input Channel A inverting input; common-mode input voltage (V-)-0.2V to (V+)-1.5V.
3 +IN A input Channel A non-inverting input; common-mode input voltage (V-)-0.2V to (V+)-1.5V.
4 V- power_in Negative power supply; ground reference; (V-) with respect to this pin defines the lower voltage rail.
5 +IN B input Channel B non-inverting input; common-mode input voltage (V-)-0.2V to (V+)-1.5V.
6 -IN B input Channel B inverting input; common-mode input voltage (V-)-0.2V to (V+)-1.5V.
7 OUT B output Channel B output; voltage swing from (V-)+0.001V to (V+)-0.75V.
8 V+ power_out Positive power supply; accepts 2.7V to 36V single supply or ±1.35V to ±18V dual supply.
