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

AMC1400QDWLRQ1 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, specified at 3 V to 5.5 V relative to GND1 (5 V nominal) with an absolute maximum of -0.3 V to 6.5 V, and needs the decoupling described in the Power Supply Recommendations section. |
| 2 | INP | input | Noninverting analog input that must have a DC current path to GND1 (with INN) to define the common-mode input voltage, which is recommended between -0.16 V and VDD1 - 2.1 V, with absolute input limits of GND1 - 6 V to VDD1 + 0.5 V. |
| 3 | INN | input | Inverting analog input that must have a DC current path to GND1 (with INP) to define the common-mode input voltage, which is recommended between -0.16 V and VDD1 - 2.1 V, with absolute input limits of GND1 - 6 V to VDD1 + 0.5 V. |
| 4 | GND1 | power_in | High-side analog ground reference for VDD1 and the input circuitry. |
| 5 | GND2 | power_in | Low-side analog ground reference for VDD2 and the output circuitry. |
| 6 | OUTN | output | Inverting analog output referenced to GND2, with a capacitive load limit of 500 pF to GND2 and 250 pF between OUTP and OUTN. |
| 7 | OUTP | output | Noninverting analog output referenced to GND2, with a capacitive load limit of 500 pF to GND2 and 250 pF between OUTP and OUTN. |
| 8 | VDD2 | power_in | Low-side power supply, specified at 3 V to 5.5 V relative to GND2 (3.3 V nominal) with an absolute maximum of -0.3 V to 6.5 V, and needs the decoupling described in the Power Supply Recommendations section. |
