Description

The TSL230R−LF, TSL230AR−LF, and TSL230BR−LF 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. 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. 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% (TSL230BR−LF), ±10%

(TSL230AR−LF), or ±20% (TSL230R−LF). 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.
