Preliminary Data Sheet PS8551AL4 R08DS0123EJ0100 ANALOG OUTPUT TYPE Rev.1.00 Jun 27, 2014 OPTICAL COUPLED ISOLATION AMPLIFIER DESCRIPTION The PS8551AL4 is an optically coupled isolation amplifier that uses an IC with a high-accuracy sigma-delta A/D converter and a GaAIAs light-emitting diode with high-speed response and high luminance efficiency on the input side, and an IC with a high-accuracy D/A converter on the output side. The PS8551AL4 is designed specifically for high common mode transient immunity (CMTI) and high linearity (non- linearity). The PS8551AL4 is designed for current and voltage sensing. FEATURES PIN CONNECTION Non-linearity (NL200 = 0.35% MAX.) (Top View) High common mode transient immunity (CMTI = 10 kV/s MIN.) High isolation voltage (BV = 5 000 Vr.m.s.) 1. VDD1 8 7 6 5 2.
