# OPA172IDBVT

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

OPA172IDBVT 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 | Output pin of the amplifier, which the datasheet describes as rail-to-rail output. |
| 2 | V- | power_in | Negative (lowest) power supply; the total supply span (V+) - (V-) is specified from 4.5 V (±2.25 V) to 36 V (±18 V). |
| 3 | +IN | input | Noninverting input; the input range extends 100 mV below the negative rail and within 2 V of the top rail during normal operation. |
| 4 | -IN | input | Inverting input; it shares the same input range as the noninverting input, 100 mV below the negative rail to within 2 V of the top rail during normal operation. |
| 5 | V+ | power_in | Positive (highest) power supply; the total supply span (V+) - (V-) is specified from 4.5 V (±2.25 V) to 36 V (±18 V). |

## CAD (KiCad official)

- Symbol: `OPA172IDBVT`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `opa172idbvt-etched.step` / `opa172idbvt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa172idbvt.step` / `opa172idbvt.glb` are the bare package body.
