Overview
HCPL-7800A/HCPL-7800 Isolation Amplifer Data Sheet Description The Broadcom® HCPL-7800A/HCPL-7800 (hereinafter referred to as HCPL-7800(A)), isolation amplifier family is designed for current sensing in electronic motor drives.
In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7800(A).
A differential output voltage is created on the other side of the HCPL-7800(A) optical isolation barrier.
This differential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit.
Because common-mode voltage swing...
