TSL230R - TAOS

TSL230R PROGRAMMABLE LIGHTFREQUENCY CONVERTERS

The TSL230R, TSL230AR, and TSL230BR 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 sel.

Features

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), ±10% (TSL230AR), or ±20% (TSL230R). They have been temperatu.
