The Broadcom® HCPL-7840 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-7840. A differential output voltage is created on the other side of the HCPL-7840 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. Since common-mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the HCPL-7840
was designed to ignore very high common-mode transient slew rates (of at least 10 kV/μs).

Applications:

  1. Motor phase and rail current sensing
  2. Inverter current sensing
  3. Switched mode power supply signal isolation
  4. General-purpose current sensing and monitoring
  5. General-purpose analog signal isolation

Features:

  1. 15 kV/μs common-mode rejection at VCM = 1000V
  2. Compact, auto-insertable standard 8-pin DIP package
  3. 0.00025V/V/°C gain drift vs. temperature
  4. 0.3-mV input offset voltage
  5. 100-kHz bandwidth
  6. Advanced Sigma-Delta (Σ-Δ) A/D converter technology
  7. Fully differential circuit topology
  8. 0.8-μm CMOS IC technology
