OPA2156IDR 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 | OUT A | output | Output, channel A. Rail-to-rail output stage capable of sourcing/sinking up to 100 mA. |
| 2 | -IN A | input | Inverting input, channel A. Rail-to-rail input, common-mode range from (V-)-0.1 V to (V+)+0.1 V. |
| 3 | +IN A | input | Noninverting input, channel A. Rail-to-rail CMOS input with ±5 pA typical bias current. |
| 4 | V- | power_in | Negative (lowest) power supply. Total supply (V+)-(V-) range is 4.5 V to 36 V (±2.25 V to ±18 V). |
| 5 | +IN B | input | Noninverting input, channel B. Rail-to-rail CMOS input with ±5 pA typical bias current. |
| 6 | -IN B | input | Inverting input, channel B. Rail-to-rail input, common-mode range from (V-)-0.1 V to (V+)+0.1 V. |
| 7 | OUT B | output | Output, channel B. Rail-to-rail output stage capable of sourcing/sinking up to 100 mA. |
| 8 | V+ | power_in | Positive (highest) power supply. Total supply (V+)-(V-) range is 4.5 V to 36 V (±2.25 V to ±18 V), or up to 40 V single-supply. |
