M52957AFP Datasheet | Hitachi Semiconductor

Description M52957AFP is a semiconductor integrated circuit containing distance detection signal processing circuit for 3V supply voltage. This device transforms each optical inflow current I1 and I2 from PSD SENSOR into the voltage, and integrates that output after doing calculation corresponds to I1/(I1+I2), and outputs it as the time data(pulse term). Features - Wide supply voltage range Vcc=2.2 to 5.5V - Includes clamp level switching circuit (Switch is 16 kinds by outside control) - Includes STANDBY function - Includes POWER ON RESET function Application Auto focus control for the CAMERA Sensor for short distance etc Remended Operating Condition Rated supply voltage - - - - - - - - - - - - - - - 3.0V Supply voltage - - - - - - - - - - - - - - - 2.2 to 5.5V Rev.1.0, Sep.19.2003, page 1 of 13 Pin Configuration PSDN CHN Vcc (TESTN) NC 1 2 16 15 PSDF CHF GND1 (TESTF) NC 3 4 5 6 7 8 14 13 12 11 10 9 STB CINT RESET SOUT GND2 CLALV HOLD...
