DISTANCE DETECTION SIGNAL PROCESSING FOR 3V SUPPLY VOLTAGE

DESCRIPTION

PIN CONFIGURATION (TOP VIEW)

M52957FP is

a semiconductor integrated circuit containing

distance detection signal processing circuit for 3V supply voltage.

This device transforms each optical inﬂow current I1 and I2 from

PSD SENSOR into the voltage, and integrates that output after

doing calculation corresponds to I1/(I1+I2), and outputs it as the

time data(pulse term).
