Texas Advanced Optoelectronic Solutions (TAOS) is based in Plano, Texas. Established in 1998, the company mission is to develop, manufacture, and market wide range of integrated optoelectronic products. TAOS’ intelligent opto sensors simplify analog-to-digital conversion of light and are designed to reduce the need for signal conditioning or preprocessing circuitry in light-centric systems. TAOS’ light sensing solutions improve system performance and reduce design cycle time giving designers the flexibility they require. TAOS opto sensor can be found in automotive, medical, industrial electronics and in home and office devices. TAOS offers a broad portfolio of Light-to-Voltage converters, Light-to-Frequency converters, Light-to-Digital converters, Linear sensor arrays, Reflective light sensors and Color sensors.

Light-to-Voltage Converters

   TAOS Inc’s Light-to-Voltage (LTV) solutions combine a photodiode and transimpedance amplifier on a single monolithic IC. The LTV family provides a linear analog voltage output that is proportional to light intensity which is normally fed to an ADC for digital processing. This output can be connected directly to an ADC for digital processing, a comparator for thresholding or other analog circuitry for filtering or further processing.

  Light-to-Frequency sensors convert light intensity to a digital format for a direct interface to a microcontroller or digital signal processor. The output of this device is a square wave or pulse train whose frequency is linearly proportional to light intensity. The TSL230R programmable Light-to-Frequency Converter is a prime example of an Intelligent Opto Sensor because it not only outputs light intensity information but also provides programming capability for adjustment of the input sensitivity and output frequency scaling. The TSL237 combines enhanced sensitivity with ultra-low dark signal giving the ability to sense a wide range of light down to ultra-low light levels (0.00002 Lux) undetectable by most silicon-based sensors.

  TAOS’ family of CMOS Linear Sensor Arrays provides the capability of measuring spatial relationships in addition to light intensity. The family is made up of a number of devices that differ by their spatial resolution (dots per inch) and/or the number of pixels. Devices are available in 200, 300 and 400 dots per inch (DPI) and array lengths from 64 to 1536 pixels. Applications include edge detection, liquid level detection, contact image sensing, optical character recognition, object measurement, and spectroscopy in applications such as copiers, document scanners, automobiles, optical rotary encoders, and medical equipment.

     Next generation of opto sensors are direct Light-to-Digital converters. Each device combines one broadband photodiode (visible plus infrared) as Channel 0 and one infrared-responding photodiode as Channel 1 on a single CMOS integrated circuit. TAOS’ patented silicon design uses the digital output of Channel 1 to compensate for the effect of the infrared component on Channel 0. Thereby, the human eye response (Lux) is derived without the use of an expensive photopic filter. With integrated analog-to-digital conversion circuitry, data is output via a serial interface using two standard protocols: SMBus and I2C. This family of devices is ideal for use with notebooks, tablets, flat-panel televisions, cell phones, and digital cameras and everywhere that small dimensions are needed. Other applications include street light control, security lighting, sunlight harvesting, machine vision, and automotive instrumentation clusters.

        The TCS230 Programmable Color Light-to-Frequency Converter combines configurable color filtered silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The TCS230 reads an 8x8 array of photodiodes, 16 of which have red filters, 16 have blue filters, 16 have green filters, and 16 are unfiltered. The color-filtered sensors are uniformly distributed across the sensing area creating four separate channels and eliminating the need for a diffuser. The device output is a square wave (50% duty cycle) whose frequency is directly proportional to the light intensity incident on the red, green, blue, or unfiltered channel. An internal multiplexer allows selection of any of the four channels to be sent to the output pin. The TCS230 interfaces directly to a microcontroller or DSP and is available in an 8-pin SOIC package.
