TI introduces industry's first SAR ADC with SPICE model

[ ]

Model enables designers to quickly simulate, model and test the full analog signal chain

DALLAS, May 21, 2012 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NASDAQ: [ TXN ]) 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. For more information, visit [ www.ti.com/ads8028-pr ].

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 support
In 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.
