Спектроскопия

Описание:
The ultra-mobile near-infrared (NIR) spectrometer reference design utilizes Texas Instruments' DLP technology in conjunction with a single-element InGaAs detector to deliver high performance measurements in a portable form factor that is more affordable than architectures using an expensive InGaAs array detector or fragile rotating grating architectures. The reference design supports Bluetooth low energy to enable mobile lab measurements for hand-held spectrometers for applications including food, agriculture, pharmaceuticals, petrochemicals, and more. Using a TI Tiva processor, databases in the cloud can be leveraged through cellular networks for real-time lab equivalent analytics, which allow food or skin analysis and wearable health monitor solutions. Developers can also create their own data collection and analysis through innovative iOS and Android applications.

Возможности:

Acquire spectrum transmittance data across a 900 to 1700 nm wavelength range in less than 1 second with >6,000:1 signal-to-noise ratio (SNR) Single element InGaAs detector design delivers high light throughput combined with a more affordable price point compared to InGaAs arrays Blue-tooth Low Energy to support wireless connectivity of spectrum data to any mobile device Programmable wavelength filtering enables constant SNR scans, on-the-fly wavelength and resolution adjustment, and chemometric algorithms High resolution spectrum acquisition with up 1824 data points Robust MEMS-based design eliminates moving gratings or mirrors for portable equipment

Описание:
This reference design features the industry's first zero-crossover and zero-drift amplifier (OPA388) to buffer the analog output of a digital-to-analog converter (DAC). It demonstrates the importance of the zero-crossover and zero-drift feature and how they can minimize the integral non-linearity (INL) of the system as well as make use of the full-scale range of the DAC (DAC8830).
Возможности:

Precision DAC (DAC8830) provides excellent linearity, low glitch, low noise and fast setting Operates at 2.7-5.5 V single-supply, which is compatible with most DSP/MCU power requirements Zero-crossover, zero-drift op amp (OPA388) provides true precision to minimize contributions to DAC INL (<0.5 LSB)
