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 offers superior reliability
compared with the traditional solutions such as current
transformers and Hall-effect sensors. These devices consist of a
sigma-delta analog-to-digital 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 can be purchased as a
commercial product (HCPL-7850), with full MIL-PRF-38534
Class H testing (HCPL-7851), with MIL-PRF-38534 Class E testing
(ACPL-785E) (Class K with exceptions) or from the DLA Standard
Microcircuit Drawing (SMD) 5962-97557. Details of the Class E
program exceptions are listed here:
1. Nondestructive Bond Pull, Test method 2023 of
MIL-STD-883 in screening is not required.
2. Particle Impact Noise Detection (PIND), Test method 2020
of MIL-STD-883 in device screening and group C testing is
not required.
3. Die Shear Strength, Test method 2019 of MIL-STD-883 in
group B testing is not required.
4. Internal Water Vapor Content, Test method 1018 of
MIL-STD-883 in group C is not required.
5. Scanning Electron Microscope (SEM) inspection, Test
method 2018 of MIL-STD-883 in element evaluation is not
required.
