LM2902BQPWRQ1 from Texas Instruments, in a TSSOP-14. 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 | OUT1 | output | Output of operational amplifier 1, voltage swing range from 100mV to 1.5V relative to supply rails. |
| 2 | IN1- | input | Inverting input of operational amplifier 1, valid common-mode voltage range V- to (V+) - 1.5V. |
| 3 | IN1+ | input | Noninverting input of operational amplifier 1, valid common-mode voltage range V- to (V+) - 1.5V. |
| 4 | V+ | power_in | Positive supply voltage terminal, recommended operating range 3V to 36V relative to V-. |
| 5 | IN2+ | input | Noninverting input of operational amplifier 2, valid common-mode voltage range V- to (V+) - 1.5V. |
| 6 | IN2- | input | Inverting input of operational amplifier 2, valid common-mode voltage range V- to (V+) - 1.5V. |
