BROADCOM HCPL7840300E Isolation Amplifier
The HCPL-7840-300E is an isolation amplifier designed for current sensing in electronic motor drives. It measures the voltage drop across an external resistor to sense motor current, providing a differential output voltage across an optical isolation barrier. This output is proportional to the motor current and can be converted to a single-ended signal using an operational amplifier. The device is capable of ignoring high common-mode transient slew rates up to 10 kV/μs, making it suitable for modern switching inverter motor drives that experience rapid voltage swings. Key features include 15 kV/μs common-mode rejection at 1000 V, 0.00025 V/V/°C gain drift over temperature, 0.3 mV input offset voltage, 100 kHz bandwidth, 0.004% nonlinearity, and a fully differential circuit topology. Applications include motor drive and control, sensing and instrumentation, and power management. Due to high market demand, lead times may be extended, and delivery dates are subject to fluctuation.
