OPA2991IPWR from Texas Instruments, in a TSSOP-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 | Output of channel A. |
| 2 | -IN A | input | Inverting input of channel A; differential input range extends to the full 40-V supply span. |
| 3 | +IN A | input | Noninverting input of channel A; common-mode range extends 100 mV beyond either supply rail. |
| 4 | V- | power_in | Negative (lowest) supply; total supply (V+)-(V-) rated 2.7 V to 40 V. |
| 5 | +IN B | input | Noninverting input of channel B; common-mode range extends 100 mV beyond either supply rail. |
| 6 | -IN B | input | Inverting input of channel B; differential input range extends to the full 40-V supply span. |
| 7 | OUT B | output | Output of channel B. |
| 8 | V+ | power_in | Positive (highest) supply; total supply (V+)-(V-) rated 2.7 V to 40 V, with a 0.1 µF bypass capacitor recommended nearby. |
