TI introduces industry’s first SAR ADC with SPICE model
Texas Instruments Incorporated today introduced a successive-approximation-register (SAR) analog-to-digital converter (ADC) with a downloadable TINA-TI SPICE model, enabling system designers to simulate and characterize the full analog signal chain in software for the first time. The model is available for the new 12-bit, 1-MSPS, 8-channel ADS8028, a highly-integrated SAR ADC featuring a low-drift internal voltage reference, wide external analog voltage reference range, wide analog and digital supply ranges, and an internal temperature sensor. Designers could previously only simulate, model and test up to the SAR ADC, requiring them to invest time and resources building the ADC circuit in hardware. With a downloadable TINA-TI SPICE model available for all new SAR ADCs, designers will be able to fully verify ADC driving circuitry, enabling them to speed product development. The ADS8028 is available today in a 4-mm x 4-mm QFN package for a suggested retail price of US$3.25 in 1,000-unit quantities.
