# OPA377AIDCKR

**Texas Instruments** · Operational Amplifier · SC-70-5

OPA377AIDCKR 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 | Noninverting input; common-mode range extends from (V-) - 0.1V to (V+) + 0.1V, and input current should be limited to 10mA or less. |
| 2 | V- | power_in | Negative supply (ground in single-supply use); total supply VS = (V+) - (V-) is specified 2.2V to 5.5V with 7V absolute maximum. |
| 3 | -IN | input | Inverting input; input is diode-clamped to the supply rails and current should be limited to 10mA or less. |
| 4 | OUT | output | Amplifier output with rail-to-rail swing, short-circuit current of +30/-50 mA, and unity-gain drive of up to 250pF capacitive load. |
| 5 | V+ | power_in | Positive supply, specified 2.2V to 5.5V total supply; decouple with a 0.1µF bypass capacitor placed close to the pin. |
