PSD ON CHIP DISTANCE DETECTION SIGNAL PROCESSOR
DESCRIPTION
M52959FP is a semiconductor integrated circuit built-in PSD(Position Sensitive Device) and distance detection
signal processor for 3V supply voltage.
This device transforms each signal current(I1 and I2) from PSD sensor to the voltage, and outputs it as the 4
Zone data after doing calculation of I1/(I1+I2).
FEATURES
PSD on chip (Sensor size=0.5mm x 0.7mm)
Wide operating supply voltage range Vcc=2.0V to 5.5V
Built-in clamp circuit
APPLICATION
Auto focus control for the CAMERA
Sensor for short distance
RECOMMENDED OPERATING CONDITION
Supply voltage
