M52957AFP is a semiconductor integrated circuit containing distance detection signal processing circuit for 3V supply voltage.
This device M52957AFP 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).
