M61006FP DISTANCE DETECTION SIGNAL PROCESSING FOR 3 V SUPPLY VOLTAGE REJ03F0039-0100Z Rev.1.0 Sep.16.2003 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 Block Diagram CV Vcc1 5 CHN Capacitance for stationary lihgt hold Vcc2 12 NC 16 TESTN 0.032 µF AFOUT 1 DIELECTRIC DIVIDEPOLE MEASURES CIRCUIT TEMPERATURE DETECTION CIRCUIT 1 µF 15 I1 OUTPUT CIRCUIT 14 PSDN PSD STATIONARY LIGHT REMOVE I/V TRANSFORM AMP RECKON I1 I1 + I2 HOLD HOLD I2 INFINITY JUDGE CIRCUIT 9 NC PSDF 11 CHF 1 µF Capacitance for stationary lihgt hold STATIONARY LIGHT REMOVE I/V TRANSFORM AMP HOLD CL...
