DESCRIPTION

The PS8551L4 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 a high-accuracy D/A conversion

function.

The PS8551L4 is designed specifically for high common mode transient immunity (CMR) and high linearity (non-

linearity). The PS8551L4 is suitable for current sensing in motor drives.

FEATURES
