The TSL230RD, TSL230ARD, and TSL230BRD programmable light-to-frequency converters combine a
configurable silicon photodiode and a current-to-frequency converter on single monolithic CMOS integrated
circuit. The output can be either a pulse train or a square wave (50% duty cycle) with frequency directly
proportional to light intensity. Device sensitivity is selectable in three ranges, providing two decades of
adjustment. The full-scale output frequency can be scaled by one of four preset values. All inputs and the output
are TTL compatible, allowing direct two-way communication with a microcontroller for programming and output
interface. The output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a
microcontroller input line.
The devices are available with absolute output frequency tolerances of ±10% (TSL230BRD), ±15%
(TSL230ARD), and ±20% (TSL230RD). They have been temperature compensated for the ultraviolet-to-visible
light range of 320 nm to 700 nm and respond over the light range of 320 nm to 1050 nm. The devices are
characterized over the temperature range of −25°C to 70°C.
