Miniature Isolation Amplifiers 0.3 mV Input Offset Voltage

Description The ACPL-C78A/C780/C784 family of isolation amplifers is designed for current sensing in electronic motor drives. In a typical implementation, motor currents ?ow through an external resistor and the resulting analog voltage drop is sensed by the ACPL-C78A/C780/C784. A di?erential outp
