Hitachi M61006FP
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.DESCRIPTION
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
