ACPL-785E , HCPL-7850, HCPL-7851, 5962-97557 Hermetically Sealed Analog Isolation Amplifier Data Sheet Description The HCPL-7850, HCPL-7851 and ACPL-785E are isolation amplifiers that provide accurate, electrically isolated and amplified representations of voltage and current. When used with a shunt resistor to monitor the motor phase current in a high speed motor drive, the device will offer superior reliability compared with the traditional solutions such as current transformers and Hall-effect sensors. These devices consist of a sigma-delta analog-todigital converter optically coupled to a digital-to-analog converter in a hermetically sealed package.
