Texas Instruments is expanding its near-infrared (NIR) chipset portfolio with a fully programmable MEMS chipset that powers up embedded ultra-mobile NIR analysis with a 700nm-to-2,500nm window transmittance.

The DLP chipset is equipped with the DLP2010NIR digital micro-mirror device (DMD), a small DLP chip designed for handheld NIR sensing applications, such as spectrometry and chemical analysis. Combined with a single point detector, it provides greater signal capture than linear array systems and supports accurate spectral analysis. The chipset enables >10,000:1 signal-to-noise ratio compared with other mobile spectroscopy systems.

In addition to the DLP2010NIR DMD, the chipset also consists of the DLPA2005 integrated power management and the DLPC150 controller, enabling low power consumption, programmable high-speed patterns and high-tilt 5.4μm pixel size for compact, side-illuminated optical designs suitable for handheld or embedded systems. Its high-speed 854x480 micro-mirror array, on the other hand, allows advanced filtering for fast measurements in handheld applications.

The chipset can also be paired with the Bluetooth and Bluetooth low energy-enabled DLP NIRscan Nano evaluation module (EVM). The EVM's leading cost point for laboratory analytics, according to TI, makes it accessible to electronics and software developers as well as iOS and Android app developers. The EVM also features fast and efficient charging with the bq24250.

The DLP2010NIR and DLPC150 will be available for purchase in April 2015, and the DLP NIRscan Nano EVM will be available spring 2015. The DLP2010NIR will be offered in a 40-pin package, and the DLPC150 will be available in a 201-pin VFBGA package. The bq24250 battery charger is currently available in a 4mm x 4mm 24VQFN-pin, 2.4mm x 2mm 30DSBGA package.
