description
The TSL230, TSL230A, and TSL230B programmable light-to-frequency converters combine a configurable
silicon photodiode and a current-to-frequency converter on single monolithic CMOS integrated circuits. The
output can be either a pulse train or a square wave (50% duty cycle) with frequency directly proportional to light
intensity. The sensitivity of the devices 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. An output enable (OE) is provided that 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
±
5% (TSL230B),
±
10% (TSL230A), or
±
20% (TSL230). Each circuit has been temperature compensated for
the ultraviolet-to-visible-light range of 300 nm to 700 nm. The devices are characterized for operation over the
temperature range of –25
°
C to 70
°
C.
