Distance Detection Signal Processing for 3V Supply Voltage
REJ03F0069-0100Z
Rev.1.0
Sep.19.2003
Description
M52957AFP 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).
Features
•
Wide supply voltage range Vcc=2.2 to 5.5V
•
Includes clamp level switching circuit
(Switch is 16 kinds by outside control)
•
Includes STANDBY function
•
Includes POWER ON RESET function
Application
Auto focus control for the CAMERA
Sensor for short distance etc
Recommended Operating Condition
Rated supply voltage • • • • • • • • • • • • • • • 3.0V
Supply voltage • • • • • • • • • • • • • • • 2.2 to 5.5V
