# OPA2365AID

**Texas Instruments** · Operational Amplifier · SOIC-8

OPA2365AID from Texas Instruments, in a SOIC-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 | VOUTA | output | Channel A output with rail-to-rail swing within 10-20 mV of power supplies. |
| 2 | -IN A | input | Channel A inverting input, common-mode range (V-) − 0.1 V to (V+) + 0.1 V, input signal extends 100 mV beyond supply rails. |
| 3 | +IN A | input | Channel A non-inverting input, common-mode range (V-) − 0.1 V to (V+) + 0.1 V, input signal extends 100 mV beyond supply rails. |
| 4 | V- | power_in | Negative power supply voltage (minimum), 2.2 V to 5.5 V below V+ over −40°C to +125°C. |
| 5 | +IN B | input | Channel B non-inverting input, common-mode range (V-) − 0.1 V to (V+) + 0.1 V, input signal extends 100 mV beyond supply rails. |
| 6 | -IN B | input | Channel B inverting input, common-mode range (V-) − 0.1 V to (V+) + 0.1 V, input signal extends 100 mV beyond supply rails. |
| 7 | VOUTB | output | Channel B output with rail-to-rail swing within 10-20 mV of power supplies. |
| 8 | V+ | power_in | Positive power supply voltage (maximum), 2.2 V to 5.5 V above V- over −40°C to +125°C. |
