PS9551L4
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
• BSI approved: No. 8937, 8938
• SEMKO approved: No. 611507
• NEMKO approved: No. P06207243
• DEMKO approved: No. 313935
• FIMKO approved: No. FI 22827
• DIN EN60747-5-2 (VDE0884 Part2) approved (Option)
APPLICATIONS
• AC Servo, inverter
• Measurement equipment

*1 The data hold time is that MDAT will stay stable following the rising edge of MCLK.
*2 CMRRIN is defined as the ratio of the differential signal gain (apply the differential signal between VIN+ and VIN−) to
the isolation-mode gain (connect both input pins to GND1 and apply the signal between (PS9551L4’s) input and
output) at 60 Hz. This value is indicated in dB.
