OPA380AID 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 | NC | unconnected | No internal connection; leave unconnected on the PCB. |
| 2 | -In | input | Inverting input; common-mode range V− to (V+)−1.8V; input bias current max ±50 pA; ESD-diode clamped to supply rails, limit over-range current to 10 mA. |
| 3 | +In | input | Non-inverting input used as fixed biasing point in transimpedance configurations; common-mode range V− to (V+)−1.8V; CMRR min 100 dB. |
| 4 | V- | power_in | Negative power supply; total supply VS = 2.7 V to 5.5 V; bypass with 1 µF ceramic or tantalum capacitor. |
| 5 | NC | unconnected | No internal connection; leave unconnected on the PCB. |
| 6 | Out | output | Voltage output; swings within 600 mV of positive rail and 100 mV of negative rail with RL = 2 kΩ; short-circuit current 150 mA; open-loop output impedance 40 Ω at 1 MHz. |
| 7 | V+ | power_in | Positive power supply; VS = 2.7 V to 5.5 V; quiescent current 7.5 mA typ, 9.5 mA max at 25°C; bypass with 1 µF ceramic or tantalum capacitor. |
| 8 | NC | unconnected | No internal connection; leave unconnected on the PCB. |
