**Texas Instruments** · Differential Amplifiers · SOIC-8

AMC1400DWLR 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 | VDD1 | power_in | High-side power supply accepting 3.3 V to 5.5 V. |
| 2 | INP | input | Noninverting differential analog input accepting ±250 mV full-scale (VFSR); requires DC current path to GND1 to define common-mode input voltage. |
| 3 | INN | input | Inverting differential analog input accepting ±250 mV full-scale (VFSR); requires DC current path to GND1 to define common-mode input voltage. |
| 4 | GND1 | power_in | High-side analog ground reference. |
| 5 | GND2 | power_in | Low-side analog ground reference. |
| 6 | OUTN | output | Inverting differential analog output with 8.2 V/V nominal gain. |
| 7 | OUTP | output | Noninverting differential analog output with 8.2 V/V nominal gain. |
| 8 | VDD2 | power_in | Low-side power supply accepting 3.3 V to 5.5 V. |
