DISTANCE DETECTION SIGNAL PROCESSING FOR 3V SUPPLY VOLTAGE
DESCRIPTION
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).
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
Supply voltage range......................................................2.2 to 5.5V
Rated supply voltage.................................................................3.0V
