Description
M61006FP is a semiconductor integrated circuit including distance detection signal processing circuit for 3 V supply
voltage. This device transforms each optical inflow current I1 and I2 from PSD SENSOR into the voltage, and
integrates the output after doing calculation corresponds to I1 / (I1+I2), and outputs it as the voltage data.
Features
•
Wide supply voltage range: Vcc = 2.2 to 5.5 V
•
Including clamp level switching circuit
(It is possible to set a clamp level to 15 points with outside control.)
•
Including infinity discrimination function
(clamp on detection function)
•
Including POWER ON RESET function
•
Including simple temperature detection function
(It is possible to correct temperature with transmitting this output to the microcomputer. )
Application
•
Auto focus control for a camera, short distance sensor, etc.
Recommended Operating Condition
•
Supply voltage range …… 2.2 V to 5.5 V
•
Rated supply voltage …… 3.0 V
