The TSL230R, TSL230AR, and TSL230BR programmable light-to-frequency converters combine a configurable silicon photodiode and a current-to-frequency converter on a monolithic integrated circuit to measure light intensity. 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 devices are available with absolute-output-frequency tolerances of ±5% (TSL230BR), ±10% (TSL230AR), and ±20% (TSL230R). They have been temperature compensated for the ultraviolet to visible light range of 320nm to 700nm and respond over the light range of 320nm to 1050nm. The devices are characterized over the temperature range of -25°C to 70°C. The devices are available in either an 8-pin plastic DIP package or an 8-pin low-profile surface mount package.

About Texas Advanced Optoelectronic (TAOS), Inc. : Shaping the Future of Light Sensing Solutions

Texas Advanced Optoelectronic Solutions, Incorporated (TAOS) is based in Plano, Texas (a suburb of Dallas). Established in 1998, the company mission is "To Redefine Optoelectronic Solutions to Provide Cost and Performance Advantages by Creating and Managing Technology."

Historically, applications that require the sensing of light stimulus to execute a function have been implemented by either a photodiode or phototransistor – neither of which support the emerging needs for higher performance optical sensor-based applications.

Utilizing state-of-the-art technology, our semiconductor devices combine precision mixed-signal functionality with photo-detectors on the same integrated circuit to produce products with performance and cost advantages over conventional solutions. TAOS's intelligent opto sensors simplify the measurement and analog-to-digital conversion of light, and are designed to reduce the need for signal conditioning or pre-processing circuitry in light-centric systems. Our light sensing solutions improve system performance and reduce design-cycle time giving designers the flexibility and performance they require at an attractive system cost.
