PRELIMINARY DATA SHEET PHOTOCOUPLER PS9551L4 HIGH CMR, DIGITAL OUTPUT TYPE OPTICAL COUPLED ISOLATION AMPLIFIER (SIGMA-DELTA MODULATOR) DESCRIPTION The PS9551L4 is an optical coupled isolation amplifier that uses an IC provided with a high-accuracy A/D conversion function (sigma-delta modulation method) and a GaAIAs light-emitting diode with high-speed response and high luminance efficiency on the input side. On the output side IC provided with an encoding function. The PS9551L4 is designed specifically for high common mode transient immunity (CMR) and high linearity (nonlinearity). The PS9551L4 is suitable for current sensing in motor drives. −NEPOC Series− FEATURES • Non-linearity (INL = 30 LSB MAX.) • High common mode transient immunity (CMR = 10 kV/μs MIN.
