# OPA171AIDBVT

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

OPA171AIDBVT 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 the datasheet describes as rail-to-rail, and which is rated for continuous short-circuit to ground under the absolute maximum conditions. |
| 2 | V- | power_in | Negative (lowest) power supply pin; the input common-mode range extends down to V- minus 0.1 V. |
| 3 | +IN | input | Non-inverting input; the normal common-mode input range is V- minus 0.1 V to V+ minus 2 V, and input current should be limited to 10 mA if the input is driven beyond the supply rails. |
| 4 | -IN | input | Inverting input; input current is absolutely limited to ±10 mA, and the datasheet recommends limiting it to 10 mA or less for fast input ramps that forward-bias the protection diodes. |
| 5 | V+ | power_in | Positive (highest) power supply pin; recommended supply range is 4.5 V to 36 V (±2.25 V to ±18 V), with a 40 V absolute maximum. |
