# TLV2471AQDRG4Q1

**Texas Instruments** · Operational Amplifier · SOIC-8

TLV2471AQDRG4Q1 from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | No internal connection. |
| 2 | IN− | input | Inverting input of the amplifier; the common-mode input voltage range is 0 V to VDD relative to GND and the differential input voltage is limited to ±VDD. |
| 3 | IN+ | input | Non-inverting input of the amplifier; the common-mode input voltage range is 0 V to VDD relative to GND and the differential input voltage is limited to ±VDD. |
| 4 | GND | power_in | Ground reference for the device; all voltages except differential voltages are specified with respect to GND. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Amplifier output, which swings to within 180 mV of each supply rail while driving a 10-mA load and can supply ±35 mA at 500 mV off the rail for non-RRO applications. |
| 7 | VDD | power_in | Positive supply, specified for a single-supply range of 2.7 V to 6 V with an absolute maximum of 7 V. |
| 8 | NC | unconnected | No internal connection. |
