Dallas, TX Designed for advanced, real-time applications in automated test equipment, medical imaging, optical networking, high-speed control loops and high-resolution data acquisition systems, Texas Instruments Incorporated's 16-bit, successive-approximation (SAR) analog-to-digital converter (ADC) offers impressive stability in challenging environments.
The ADS8372 provides 16-bit no missing code performance, 600kSPS data rate, less than 0.75LSB maximum integral nonlinearity (INL) and less than 0.5LSB maximum differential nonlinearity (DNL) between -40degreesC to +85degreesC. The ADC also has on-chip reference and reference buffer, improving signal linearity without the need for active external components.
The ADS8372 features a fully differential, pseudo-bipolar input range and includes a 16-bit capacitor-based SAR ADC architecture with inherent sample and hold, 4.096V internal reference, internal reference buffer and conversion clock. The ADC also offers a high-speed CMOS, SPI-compatible serial interface with clock speeds up to 40MHz. A pseudo-differential, unipolar version is also available in the ADS8370.
Other key specifications include +/-0.2ppm/degreesC offset drift, 94dB signal-to-noise ratio (SNR), 120dB spurious-free dynamic range (SFDR) and 110mW power consumption at 600 kSPS (only 15mW during nap mode and 10 microWatts during power down).
Evaluation modules are available for the ADS8372, which costs $13.00 in 1,000-piece quantities. Click here for the data sheet.
