# OPA2377AIDGKT

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

OPA2377AIDGKT 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 | Amplifier A output, rail-to-rail, with continuous short-circuit current to ground of +30/-50 mA (one amplifier per package). |
| 2 | -IN A | input | Amplifier A inverting input, diode-clamped to the supply rails; signals more than 0.5V beyond the rails must be current limited to 10 mA or less. |
| 3 | +IN A | input | Amplifier A noninverting input, diode-clamped to the supply rails, with a common-mode range of (V-) - 0.1V to (V+) + 0.1V. |
| 4 | V- | power_in | Negative supply (ground in single-supply use); total supply VS = (V+) - (V-) is specified 2.2V to 5.5V with an absolute maximum of 7V. |
| 5 | +IN B | input | Amplifier B noninverting input, diode-clamped to the supply rails, with a common-mode range of (V-) - 0.1V to (V+) + 0.1V. |
| 6 | -IN B | input | Amplifier B inverting input, diode-clamped to the supply rails; signals more than 0.5V beyond the rails must be current limited to 10 mA or less. |
| 7 | OUT B | output | Amplifier B output, rail-to-rail, with continuous short-circuit current to ground of +30/-50 mA (one amplifier per package). |
| 8 | V+ | power_in | Positive supply, specified 2.2V to 5.5V total supply with an absolute maximum of 7V, and should be bypassed with a 0.1 µF capacitor close to the pin. |
