# OPA377AIDCKT

**Texas Instruments** · Precision Op Amps · SC-70-5

OPA377AIDCKT from Texas Instruments, in a SC-70-5. 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 | +IN | input | Non-inverting input; common-mode range is (V-) - 0.1V to (V+) + 0.1V and input current must be limited to 10mA if signals swing more than 0.5V beyond the rails. |
| 2 | V- | power_in | Negative supply or ground in single-supply use; total supply VS = (V+) - (V-) is specified from 2.2V to 5.5V with 7V absolute maximum. |
| 3 | -IN | input | Inverting input; common-mode range is (V-) - 0.1V to (V+) + 0.1V and input current must be limited to 10mA if signals swing more than 0.5V beyond the rails. |
| 4 | OUT | output | Rail-to-rail amplifier output with continuous short-circuit current to ground (ISC +30/-50mA) and unity-gain drive of up to 250pF capacitive load. |
| 5 | V+ | power_in | Positive supply, specified from 2.2V to 5.5V total supply with a 0.1µF bypass capacitor to ground placed close to the pin. |
