Optically Isolated Delta-Sigma Modulator

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 Sinc³digital 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.)

PIN CONNECTION

• Effective Number of Bit (ENOB = 12 bits TYP.)

(Top View)

• Operating Ambient Temperature (TA = −40 to 105°C)

• Non-linearity (INL = 0.14％ MAX.)

2. VIN+

• 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)
