Description
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.
