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. |
