Photodetector with frequency converter 1 000 kHz | TSL230ARD
TAOS
The TSL230RD programmable light-to-frequency converter combines a configurable silicon photodiode and a current-to-frequency converter on a 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. The sensitivity of the device 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.
