HIGH CMR, DIGITAL OUTPUT TYPE
OPTICAL COUPLED ISOLATION AMPLIFIER
(SIGMA-DELTA MODULATOR)
NEPOC Series
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 (non-
linearity). The PS9551L4 is suitable for current sensing in motor drives.
FEATURES
• Non-linearity (INL = 30 LSB MAX.)
• High common mode transient immunity (CMR = 10 kV/μs MIN.)
• High isolation voltage (BV = 5 000 Vr.m.s.)
• Package: 8-pin DIP lead bending type (Gull-wing) for long creepage distance
for surface mount (L4)
• Ordering number of tape product: PS9551L4-E3: 1 000 pcs/reel
• Pb-Free product
• Safety standards
• UL approved: File No. E72422
• CSA approved: No. CA 101391
