High CMR Isolation Amplifiers

Description The HCPL-7800 high CMR isolation amplifier provides a unique combination of features ideally suited for motor control circuit designers. The product provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for

15 kV/關s Common-Mode Rejection at VCM = 1000 V

Description The HCPL-7800(A) isolation amplifer family was designed for current sensing in electronic motor drives. In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7800(A). A differential output voltage is cre
