# TLV2771IDR

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

TLV2771IDR 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 (NC) on the TLV2771 D package. |
| 2 | IN− | input | Inverting input of the amplifier; the input voltage range is GND to VDD − 1.3 V over the recommended operating conditions, and input current is limited to ±4 mA absolute maximum. |
| 3 | IN+ | input | Noninverting input of the amplifier; the input voltage range is GND to VDD − 1.3 V over the recommended operating conditions, and input current is limited to ±4 mA absolute maximum. |
| 4 | GND | power_in | Ground reference; all voltages in the datasheet, except differential voltages, are referenced to GND. |
| 5 | NC | unconnected | No internal connection (NC) on the TLV2771 D package. |
| 6 | OUT | output | Amplifier output; output current is limited to ±50 mA absolute maximum, and the device is rail-to-rail output with unlimited duration of short-circuit current at or below 25°C. |
| 7 | VDD | power_in | Positive single-supply voltage; recommended supply range is 2.5 V to 6 V (absolute maximum 7 V). |
| 8 | NC | unconnected | No internal connection (NC) on the TLV2771 D package. |
