A Business Partner of Renesas Electronics Corporation. Preliminary Data Sheet PS8551L4 R08DS0039EJ0200 Rev.2.00 ANALOG OUTPUT TYPE Sep 06, 2011 OPTICAL COUPLED ISOLATION AMPLIFIER DESCRIPTION The PS8551L4 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 PS8551L4 is designed specifically for high common mode transient immunity (CMTI) and high linearity (non- linearity). The PS8551L4 is suitable for current sensing in motor drives. 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.
