# TLV9161QDCKRQ1

**Texas Instruments** · Operational Amplifier · SC-70-5

TLV9161QDCKRQ1 from Texas Instruments, in a SC-70-5. 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 | IN+ | input | Noninverting input of the amplifier; the common-mode range extends to both supply rails (V- to V+). |
| 2 | V- | power_in | Negative (lowest) power supply; supply voltage is specified as (V+) - (V-) from 2.7 V to 16 V. |
| 3 | IN- | input | Inverting input of the amplifier. |
| 4 | OUT | output | Amplifier output, which limits into the appropriate supply rail when overdriven. |
| 5 | V+ | power_in | Positive (highest) power supply; supply voltage is specified as (V+) - (V-) from 2.7 V to 16 V. |
