OPA1641AIDGKR from Texas Instruments, in a VSSOP-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 | NC | unconnected | No internal connection. |
| 2 | -IN | input | Inverting input with input bias current of ±20 pA maximum and common-mode input voltage range of (V-)-0.1 V to (V+)-3.5 V. |
| 3 | +IN | input | Noninverting input with input bias current of ±20 pA maximum and common-mode input voltage range of (V-)-0.1 V to (V+)-3.5 V. |
| 4 | V- | power_in | Negative (lowest) power supply with recommended operating range of ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Output with rail-to-rail swing from (V-)+0.2 to (V+)-0.2 V at RL=10kΩ or (V-)+0.35 to (V+)-0.35 V at RL=2kΩ, output current limits: 36 mA source and 30 mA sink. |
| 7 | V+ | power_in | Positive (highest) power supply with recommended operating range of ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply. |
| 8 | NC | unconnected | No internal connection. |
