Plano, Texas Texas Advanced Optoelectronic Solutions, Inc. (Taos) boosted the performance of two new light-to-digital converters to suit a wider range of applications.
The patented digital light sensors convert light intensity to a digital signal output capable of direct I²C or System Management Bus (Sbus) interface.
"We've increased the performance of our new digital light sensors to support not only as broad a range of ambient light sensing applications as possible, but also any type of application that requires accurate light sensing at a reasonable cost," said Glenn Lee, Taos strategic marketing specialist for ambient lighting. In addition, both devices can help designers significantly shorten time-to-market with their direct digital interface and software support, he said. "A number of customers have already designed in the TSL2560 in less than 2 to 3 months," Lee added.
The TSL2560/61 light-to-digital converters support a dynamic range of 0 to 40,000 Lux, compared to Taos' previous generation TSL2550, which supports 0 to 10,000 Lux. This allows the user to see very low light (as in keyboard illumination applications), and a very bright light to support full mobility.
In addition, the TSL2560/61 provides 16-bit linear output, versus a 7-bit companded output in the TSL2550, for increased resolution.
Also, the TSL2560/61 is the only device on the market with interrupt capability; high/low interrupt thresholds are configurable. Since the interrupt capability is also intelligent, it can accommodate sudden changes in light, such as shadows.
Available now, the TSL2560 and TSL2561 light-to-digital converters come in two standard
6-pin packages: A CSP measuring 1.7 x 1.2 x 0.7 mm and a transfer molded board (TMB) measuring 3.8 x 2.6 x 1.4 mm.
An evaluation module with a Universal Serial Bus (USB) interface is available with a suggested resale price of $125.00. The TSL2560/61 has a suggested resale price of $1.29 in 1,000-piece quantities. Click here for the TSL2560.61 data sheets.
