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 pared 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. The products are capable of operation and storage over the full military temperature range and may be purchased as a standard product (HCPL-7850), with full MIL-PRF-38534 Class H testing (HCPL-7851), with MIL-PRF-38534 Class E testing (Class K with exceptions) or from the DLA Standard Microcircuit Drawing (SMD) 5962-97557.
