Texas Instruments · Isolation Amplifiers · SOP-8

AMC1200BDUBR from Texas Instruments, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD1 power_in High-side power supply. Recommended 4.5 V to 5.5 V (nominal 5 V); absolute max 6 V referenced to GND1. Supplies the input (shunt-side) domain of the isolation barrier.
2 VINP input Noninverting analog input. ±250 mV linear differential range with VINN; input clipping above ±320 mV. Input voltage must remain within GND1 - 0.5 V to VDD1 + 0.5 V (absolute max).
3 VINN input Inverting analog input. Forms the ±250 mV differential input pair with VINP; typically tied to the low side of the shunt resistor. Differential input resistance ~28 kΩ.
4 GND1 power_in High-side (input, shunt-side) analog ground. Reference for VDD1 and the VINP/VINN input pair. Isolated from GND2 by the SiO2 barrier.
5 GND2 power_in Low-side (output, controller-side) analog ground. Reference for VDD2 and the VOUTP/VOUTN output pair. Isolated from GND1 by the SiO2 barrier.
6 VOUTN output Inverting analog output. Half of the fully-differential output pair (gain 8). Output common-mode is ~VDD2/2 (1.29 V at VDD2=3.3 V, 2.55 V at VDD2=5 V). Output resistance ~2.5 Ω.
7 VOUTP output Noninverting analog output. Half of the fully-differential output pair (gain 8). Output swings ±1 V around the output common-mode voltage. Short-circuit current ~20 mA.
8 VDD2 power_in Low-side power supply. Recommended 2.7 V to 5.5 V (nominal 3.3 V or 5 V); absolute max 6 V referenced to GND2. Supplies the controller-side (output) domain of the isolation barrier.
