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

AMC1311BQDWVQ1 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, operating range 3 to 5.5 V for AMC1311B-Q1 variant. |
| 2 | IN | input | Analog input, high-impedance, specified linear full-scale voltage range -0.1 to 2 V referenced to GND1. |
| 3 | SHTDN | input | Shutdown digital input, active high, with internal pullup resistor (typical 100 kΩ), voltage range 0 to VDD1. |
| 4 | GND1 | power_in | High-side analog ground, reference for input signal IN and high-side power supply VDD1. |
| 5 | GND2 | power_in | Low-side analog ground, reference for output signals OUTP and OUTN, and low-side power supply VDD2. |
| 6 | OUTN | output | Inverting analog output with voltage range GND2 - 0.5 to VDD2 + 0.5 V. |
| 7 | OUTP | output | Noninverting analog output with voltage range GND2 - 0.5 to VDD2 + 0.5 V. |
| 8 | VDD2 | power_in | Low-side power supply, operating range 3 to 5.5 V. |
