Texas Advanced Optoelectronic Solutions,
Inc. (TAOS), has unveiled its fifth-generation sensor family,
the TSL2x72 Series, that delivers improved digital ambient light sensing
(ALS) and proximity detection technology. The TSL2x72 Series is
especially designed to create the widest dynamic range of operation
necessary for mobile products to adapt to all lighting conditions.
The TSL2x72 Series includes three device families, including digital
ambient light sensors (TSL2572), proximity detection sensors (TSL2672)
and integrated digital ambient light and proximity detection sensors
(TSL2772). The TSL2x72 Series enhances mobile products by providing ALS
and proximity detection operation in environments over 60,000 lux
(sunlight). The improved dynamic range is enabled by the device's new
programmable gain modes, including a reduced gain mode. Proximity
detection enhancements consist of increased signal-to-noise performance
and a programmable register which allows compensation for optical signal
Power management is improved with an automatic power-down mode after
interrupt, which provides a 'run-once' capability, and further reduces
system power consumption. The TSL2x72 Series is based on the patented
TAOS dual-diode architecture, which enables the devices to produce
accurate ALS and proximity detection results when operating behind
spectrally distorting glass regardless of the lighting sources (e.g.
sunlight, fluorescent) and intensity.
The TSL2x72 devices are register
set, footprint, and pin compatible with their predecessor TSL2x71
Series. They incorporate an IR LED current-limited driver,
analog-to-digital conversion (ADC), interrupt capability, multiple I2C
interface voltage options (3.0V or 1.8V) and flexible programming
allowing it to be configured into many different applications. The
sensors are packaged in a cost-effective 2x2mm dual flat no-lead package.
