AMC1311BQDWVQ1

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.
