LIGHT-TO-FREQUENCY (LTF) from Texas Advanced Optoelectronic Solutions (TAOS), Inc.
The LTF sensor performs the functions of light sensing, signal conditioning, and A/D conversion in a single monolithic IC. The LTF device converts light intensity to a digital format for a direct interface to a microcontroller. The output of this device is a square wave or pulse train whose frequency is linearly proportional to light intensity and features a dynamic range of 120dB.
LTF converters are designed for applications such as ambient light measurement, light absorption/reflection in products such as white goods, photographic equipment, colorimetry, chemical analyzers and display contrast controls or any system requiring a wide dynamic range and/or high resolution digital measurement of light intensity.

About Texas Advanced Optoelectronic Solutions (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.
