# TLV2731IDBVR

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

TLV2731IDBVR 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 | Amplifier output, which swings rail-to-rail between VDD- and VDD+ with a resistive output stage that can drive capacitive loads when an isolation resistor is used. |
| 2 | VDD+ | power_in | Positive (highest) supply rail; the recommended supply is 2.7 V to 10 V, and the absolute maximum VDD is 12 V, all referenced to VDD-. |
| 3 | IN+ | input | Non-inverting input whose common-mode range is VDD- to VDD+ - 1.3 V under the recommended operating conditions. |
| 4 | IN- | input | Inverting input whose common-mode range is VDD- to VDD+ - 1.3 V under the recommended operating conditions. |
| 5 | VDD-/GND | power_in | Negative (lowest) supply rail, which is the voltage reference for all other pin voltages (GND in single-supply operation); the input differential voltage must not drive input current beyond limits when inputs fall below VDD- - 0.3 V. |
