AT1001Z Wide Input Range Data demodulation PWM controller

General Description
The AT1001Z is a three channel data demodulator that transfer the analog input signal into a PWM duty signal for the followed EMP(energy measurement processor).
The fourth output signal provide the phase shift information between channel one and two. AT1001Z is designed to allow for operating a wide supply voltage range from 4.5V to 24V.
The internal excellent linrarity modulation mechanism makes the converting have good line regulation with flexible external supply voltage design. The PWM signal is operated in a 5kHz switching frequency and a fixed 2k output driving impedance. The devices are available in PSOP-8L packages and require very few external devices for operation.
