Able to detect small electric current and voltage fluctuations, Models TLP7820 and TLP7920 are suitable for use in inverters, servo amplifiers, robots, and power supplies. Delta-sigma ADC at input side enables linearity of 0.02% (typ.) @ NL (200) for analog output products and 3LSB (typ.) @ INL for digital output products. With Common-Mode Transient Immunity of 20 kV/µs, optical coupled amplifiers offer stable operation in electrically noisy environments. Isolation voltage is 5,000 Vrms (min).
