제품 개요
ACPL-C797-500E is a 1bit, second-order sigma-delta modulator. It converts an analogue input signal into a high-speed data stream with galvanic isolation based on optical coupling technology. It operates from a 5V power supply with dynamic range of 80dB with an appropriate digital filter. The differential inputs of ±200mV (full scale ±320mV) are ideal for direct connection to shunt resistors or other low-level signal sources in applications, such as motor phase current measurement. The analogue input is continuously sampled by a means of sigma-delta over-sampling using an on-board clock. It is used in applications such as motor phase and rail current sensing, power inverter current and voltage sensing, industrial process control, data acquisition systems, general purpose current and voltage sensing, traditional current transducer replacements.
