Isolation Amplifer

The HCPL-7800 A) isolation amplifer family was designed for current sensing in electronic motor drives. In a typical implementation, motor currents fow through an external resistor and the resulting Analog voltage drop is sensed by the HCPL-7800 A). A diferential output voltage is created on the other side of the HCPL-7800 A) optical isolation barrier. This diferential output voltage is pro- portional 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. Since common- mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the HCPL-7800 A) was designed to ignore very high common-mode transient slew rates (of at least 10 kV/s).
