OPA2137UA 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 | Out A | output | Amplifier A output, swings to (V-)+1.2V and (V+)-1.1V at VS = ±15V with RL = 10kΩ, short-circuit current -25/+60mA, stable with up to 330pF load. |
| 2 | -In A | input | Amplifier A inverting input with ±10pA FET input bias current, clamped by diodes to the supply rails and limited to 2mA input current. |
| 3 | +In A | input | Amplifier A non-inverting input with ±10pA FET input bias current, common-mode range from (V-)+3V to (V+). |
| 4 | V- | power_in | Negative supply (or ground in single-supply use); total supply range 4.5V to 36V, dual supply ±2.25V to ±18V. |
| 5 | +In B | input | Amplifier B non-inverting input with ±10pA FET input bias current, common-mode range from (V-)+3V to (V+). |
| 6 | -In B | input | Amplifier B inverting input with ±10pA FET input bias current, clamped by diodes to the supply rails and limited to 2mA input current. |
| 7 | Out B | output | Amplifier B output, swings to (V-)+1.2V and (V+)-1.1V at VS = ±15V with RL = 10kΩ, short-circuit current -25/+60mA, stable with up to 330pF load. |
| 8 | V+ | power_in | Positive supply; total supply range 4.5V to 36V, bypass with a 10nF or larger ceramic capacitor. |
