Signal processing circuit for 1-D PSD
C3683-02
Circuit board for easier 1-D PSD operation
The C3683-02 is a DC signal processing circuit for one-dimensional PSD. It is suitable for displacement measurements using
DC light.
Features
Applications
No complicated adjustments required
Position measurement of a light spot can be made
simply by mounting 1-D PSD.
Output voltage directly representing the position data
The position (mm) of a light spot from the PSD (S3931,
S3932) center is obtained as an output voltage (V).
Displacement measurements using DC light
Various studies using 1-D PSD
Performance evaluation of 1-D PSD
Accurate position sensing
Position data of a light spot is independent of incident
light intensity.
Three sensitivity ranges
Compact design
Head amp, signal addition/subtraction circuits, and
analog divider circuit are mounted on a compact PC
board.

*1: No dew condensation
When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.

Factory setup prior to shipping is M range. The range can be switched with the jumper on the board.
Photocurrent with PSD installed. PSD does not operate correctly if the input signal current is outside the specified range.
Output response time 10 to 90%
With no PSD installed. Current signal that substitutes for PSD photocurrent (L range: X1=X2=400 μA, M range: X1=X2=40 μA,
H range: X1=X2=4 μA) is input. When maximum output amplitude voltage Vo=±6 V is set.
*6: Factory setup prior to shipping is ±6 V. Maximum output amplitude can be adjusted in a range of ±2 to ±10 V with a variable resistor
on the board according to the PSD type to be used.
*7: Factory setup prior to shipping is +5 V. The voltage can be adjusted in the range of 0 to +14 V with a variable resistor on the board.
