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.

†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to GND.
2. The device may be hand soldered provided that heat is applied only to the solder pad and no contact is made between the tip of
the solder iron and the device lead. The maximum time heat should be applied to the device is 5 seconds.

NOTES: 3. Full-scale frequency is the maximum operating frequency of the device without saturation.
4. The temperature coefficient of output frequency is measured with constant irradiance as the temperature is varied between −25°C
and 70°C. The constant irradiance is sufficiently high that the output frequency is much greater than the dark frequency over the
entire temperature range.
