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

*3 Set a current output from PHOTOCUPPLER to following input conditions, and input the varied resistance ratio. AF
slope, linearity is calculated with following equations by measuring AFOUT output voltage.
Input condition1: IPSD (Stationary light current) = 0
I1:I2 = 100 nA
Input condition2: IPSD (Stationary light current) = 0
Input condition3: IPSD (Stationary light current) = 10 µΑ
I1:I2 = 50 nA
I1:I2 = 100 nA
D (9:1)·····The AFOUT output voltage at input with I1:I2 = 9:1
D (6:4)·····The AFOUT output voltage at input with I1:I2 = 6:4
D (3:7)·····The AFOUT output voltage at input with I1:I2 = 3:7
AF slope: AF = D (9:1) – D (3:7)
AF linearity: L (AF) = (D (9:1) - (6:4) ) / (D (6:4) - (3:7) )
PSD quite resistance: 120 k
*4 Input current of one side channel without saturating stationary light remove circuit and I / V transform amplifier
circuit.
*5 Confirm not to change the output data at measuring AF input condition (1 to 4), when you shorten intervals
between stationary ray hold and distance measurement integration beginning to MIN 26 µS.
*6 The value in this item is less than “max” value at any cases.
*7 Set AFOUT capacity, distance measurement integration time, and the number of integration under max
value, because the “max” value in this item indicates a maximum of IC dynamic range.
*8 Establish optional system to be input current to IC less than standard value, because this item’s value indicates
maximum input current to IC.
