DESCRIPTION
The PS9551AL4 is an optically isolated Delta – Sigma Modulator that includes high-Accuracy A/D convertor and
converts an analog voltage input into one-bit data stream. PS9551AL4 provides Effective Number of Bit (ENOB) is 12
bits (typ) with a Sinc³ digital filter.
The PS9551AL4 is designed specifically for high common mode transient immunity (CMR) and high linearity
(nonlinearity). The PS9551AL4 is suitable for current sensing and voltage sensing in motor drives.
FEATURES
• Internal Reference Voltage Tolerance (GE = ±1% MAX.)
• Effective Number of Bit (ENOB = 12 bits TYP.)
• Operating Ambient Temperature (TA = −40 to 105°C)
• Non-linearity (INL = 0.14％ MAX.)
• Input Offset Voltage (VOS = 3 mV MAX.)
• Input Offset Voltage Drift vs. Temperature (⏐dVos/dTA⏐ = 2 μV/°C TYP.)
• Output Clock Frequency (fCLK = 10 MHz TYP.)
• High common mode transient immunity (CMR= 15 kV/μs MIN.)
• Package: 8-pin DIP lead bending type (Gull-wing) for long creepage distance for
surface mount (L4)
• Embossed tape product: PS9551AL4-E3: 1 000 pcs/reel
• Pb-Free product
