APPLICATION INFORMATION

Power-supply considerations

Power-supply lines must be decoupled by a 0.01-μF to 0.1-μF capacitor with short leads placed close to the

device package. A low-noise power supply is required to minimize jitter on output pulses.

Input interface

A low-impedance electrical connection between the device OE pin and the device GND pin is required for

improved noise immunity.

Output interface

The output of the device is designed to drive a standard TTL or CMOS logic input over short distances. If lines

greater than 12 inches are used on the output, a buffer or line driver is recommended.

Sensitivity adjustment

Sensitivity is controlled by two logic inputs, S0 and S1. Sensitivity is adjusted using an electronic iris technique

— effectively an aperture control — to change the response of the device to a given amount of light. The

sensitivity can be set to one of three levels: 1×, 10×, or 100×, providing two decades of adjustment. This allows

the responsivity of the device to be optimized to a given light level while preserving the full-scale

output-frequency range. Changing of sensitivity also changes the effective photodiode area by the same factor.
