# TLV2451CDBVR

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

TLV2451CDBVR 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 | Rail-to-rail amplifier output, with output drive capability of ±10 mA and swing to within 250 mV of each supply rail while driving a 2.5-mA load. |
| 2 | GND | power_in | Negative supply/ground terminal, with all voltage values except differential voltages referenced to it. |
| 3 | IN+ | input | Noninverting input, with common-mode input voltage range of 0 to VDD and differential input voltage limited to ±VDD. |
| 4 | IN− | input | Inverting input, with common-mode input voltage range of 0 to VDD and differential input voltage limited to ±VDD. |
| 5 | VDD+ | power_in | Positive supply, recommended 2.7 V to 6 V single supply (±1.35 V to ±3 V split) with 7 V absolute maximum. |
