THE TSL257
The TSL257 is a high-sensitivity low-noise light-to-voltage optical converter that combines a photodiode and a transimpedance amplifier on a single monolithic CMOS integrated circuit. The output voltage is directly proportional to light intensity (irradiance) on the photodiode. The TSL257 has a transimpedance gain of 320 Megohm. At 470 nm, the typical irradiance responsivity is 1300mV/µW/cm²) with an output rise and fall time of 160µsec. The device has improved offset voltage stability and low power consumption and is packaged in a 3-lead clear plastic side-looker package with integral lens.

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.
