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

AMC1411DWLR 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, 3 V to 5.5 V relative to GND1 (absolute maximum 6.5 V), with decoupling per the Power Supply Recommendations section. |
| 2 | IN | input | High-impedance analog input with specified linear full-scale range of -0.1 V to 2 V relative to GND1, clipping at 2.516 V. |
| 3 | SHTDN | input | Shutdown input, active high, with internal pullup resistor (typical 100 kΩ), input range 0 V to VDD1 referenced to GND1. |
| 4 | GND1 | power_in | High-side analog ground, reference for VDD1, IN and SHTDN. |
| 5 | GND2 | power_in | Low-side analog ground, reference for VDD2, OUTP and OUTN. |
| 6 | OUTN | output | Inverting analog output, absolute maximum GND2 - 0.5 V to VDD2 + 0.5 V. |
| 7 | OUTP | output | Noninverting analog output, absolute maximum GND2 - 0.5 V to VDD2 + 0.5 V. |
| 8 | VDD2 | power_in | Low-side power supply, 3 V to 5.5 V relative to GND2 (absolute maximum 6.5 V), with decoupling per the Power Supply Recommendations section. |
