Dallas, Texas - May 21, 2012 - Texas Instruments Incorporated today introduced a successive-approximation-register (SAR) analog-to-digital converter (ADC) with a downloadable TINA-TI(TM) 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.

Key features and benefits of the ADS8028

Tools to simulate and evaluate quickly: TINA-TI reference design and product evaluation module (EVM) include the OPA836 driver amplifier for fast software simulation and hardware evaluation.

Integration to reduce board space, bill of materials: Integrates an internal 2.5-V reference, +1 degree Celsius accurate temperature sensor and internal multiplexer with sequencer; it also eliminates the need for an external decoupling capacitor.

Widest supply ranges provide greater power supply flexibility: 3x wider analog supply range of 2.7 V to 5.25 V, 80-percent wider digital supply range of 1.65 V to 5.25 V and 2.5x wider external reference range of 1 V to 5 V, compared to the competition.

Low power consumption, small size for battery-powered, space-constrained designs: Consumes a maximum of 36 microWatts in power-down mode across a wide operating temperature range of -40 C to 125 C in a small 4-mm x 4-mm package to support battery-powered, space-constrained designs.

Feature set supports diverse applications: Low power consumption, wide temperature and supply ranges, and a high level of integration enable use in a wide variety of applications, including portable consumer electronics, wireless infrastructure and industrial equipment.

Tools and supportIn addition to the TINA-TI SPICE model, an IBIS model is available to verify board signal integrity requirements. The ADS8028EVM-PDK is also available to expedite evaluation of the new ADC. It can be ordered today for US$199.

Availability, packaging and pricing 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.
