The introduction of electric and hybrid electric vehicles have added high-voltage electric modules into the car. The battery stack in a hybrid can be in excess of 150V, higher for the inverter driving the motor.
Avago Technologies' ACPL-782T automotive isolation amplifier, which is part of the R2Coupler, integrates functions such as safe insulation, common mode transient rejection and analog sensing in a 300-mil dual-in-line package.
