# TLV171QDBVRQ1

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

TLV171QDBVRQ1 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 with rail-to-rail output swing, and the device is stable with capacitive loads up to 300 pF. |
| 2 | V- | power_in | Negative (lowest) power supply; the total supply range (V+ - V-) is 4.5 V to 36 V, with an absolute maximum supply voltage of 40 V. |
| 3 | +IN | input | Noninverting input; the input common-mode 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 common-mode range as the noninverting input, extending 100 mV below the negative rail and within 2 V of the top rail during normal operation. |
| 5 | V+ | power_in | Positive (highest) power supply; it operates with the 4.5 V to 36 V total supply range, and input signals beyond the supply rails do not cause phase reversal. |
