PS8551L4

Preliminary Data Sheet PS8551L4 ANALOG OUTPUT TYPE OPTICAL COUPLED ISOLATION AMPLIFIER DESCRIPTION R08DS0039EJ0200 Rev.2.00 Sep 06, 2011 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 (nonlinearity). The PS8551L4 is suitable for current sensing in motor drives. FEATURES Non-linearity (NL200 = 0.35% MAX.) High common mode transient immunity (CMTI = 10 kV/μs MIN.) High isolation voltage (BV = 5 000 Vr.m.s.) Gain tolerance (G = 7.76 to 8.24 (±3%)) Gain: 8 V/V TYP. Package: 8-pin DIP lead bending type (Gull-wing) for long creepage distance for surface mount (L4) Embossed tape product: PS8551L4-E3 : 1 000 pcs/reel Pb-Free product Safety standards UL approved: No. E72422 CSA approved: No. CA 101391 (CA5A, CAN/CSA-C22.2 60065, 60950) SEMKO approved: No. 1111155 DIN EN60747-5-2 (VDE0884 Part2) approved: No. 40019182 (Option) www.DataSheet.co.kr PIN CONNECTION (Top View) 8 7 + 6 – 5 SHIELD 1 2 3 4 1.
