MIL-PRF-38534 Class H, Class K, and DSCC SMD Test Program
Avago Technologies’s Hi-Rel Optocouplers are in compli-
ance with MIL-PRF-38534 Classes H and K. Class H and
Class K devices are also in compliance with DSCC draw-
ings 5962-87679, and 5962-90854. Testing consists of
100% screening and quality conformance inspection to
MIL-PRF-38534.
Description
The schematic uses a dualchannel, high-speed optocou-
pler (HCPL-5530) to function as a servo type dc isolation
amplifier. This circuit operates on the principle that two
optocouplerswilltrackeachotheriftheirgainchangesby
the same amount over a specific operating region.
Performance of Circuit
1% linearity for 10 V peak-to-peak dynamic range
Gain drift: -0.03%/°C
Offset Drift: ± 1 mV/°C
25 kHz bandwidth (limited by Op-Amps U1, U2)
