# TLV2781CDBVR

**Texas Instruments** · Operational Amplifier · SOT-23-5

TLV2781CDBVR from Texas Instruments, in a SOT-23-5. 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 | OUT | output | Single-channel amplifier output with rail-to-rail output swing between the supply rails. |
| 2 | GND | power_in | Ground reference; all voltages except differential input voltage are specified with respect to GND. |
| 3 | IN+ | input | Non-inverting input; common-mode input voltage range is −0.2 V to VDD + 0.2 V. |
| 4 | IN− | input | Inverting input; common-mode input voltage range is −0.2 V to VDD + 0.2 V, and input current is limited to ±10 mA. |
| 5 | VDD | power_in | Positive supply; recommended 1.8 V to 3.6 V single supply, with an absolute maximum of 4 V. |
