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
