OPA2189IDGKT 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 | OUT A | output | Output of channel A; rail-to-rail output voltage from V- to V+ with output swing to within 20 mV to 120 mV of each rail at 10 kΩ load. |
| 2 | -IN A | input | Inverting input of channel A; accepts differential input signals within common-mode voltage range (V-) - 0.1 V to (V+) - 2.5 V, maximum ±10 mA input current. |
| 3 | +IN A | input | Non-inverting input of channel A; accepts differential input signals within common-mode voltage range (V-) - 0.1 V to (V+) - 2.5 V, input bias current ±70 pA typical. |
| 4 | V- | power_in | Negative power supply pin (lowest potential); supply voltage range ±2.25 V to ±18 V (dual-supply) or 4.5 V to 36 V (single-supply), absolute maximum ±20 V. |
| 5 | +IN B | input | Non-inverting input of channel B; accepts differential input signals within common-mode voltage range (V-) - 0.1 V to (V+) - 2.5 V, input bias current ±70 pA typical. |
| 6 | -IN B | input | Inverting input of channel B; accepts differential input signals within common-mode voltage range (V-) - 0.1 V to (V+) - 2.5 V, maximum ±10 mA input current. |
| 7 | OUT B | output | Output of channel B; rail-to-rail output voltage from V- to V+ with output swing to within 20 mV to 120 mV of each rail at 10 kΩ load. |
| 8 | V+ | power_in | Positive power supply pin (highest potential); supply voltage range ±2.25 V to ±18 V (dual-supply) or 4.5 V to 36 V (single-supply), absolute maximum 40 V. |
