TI introduces industry's fastest 24-bit delta-sigma ADC with speeds up to 4 MSPS

Precision ADC offers 60 percent faster sample rate than nearest competition

DALLAS, March 26 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's fastest 24-bit delta-sigma analog-to-digital converter (ADC), which delivers speeds of up to four mega samples per second (MSPS) - 60 percent faster than the nearest competition. The ADS1675 features a unique combination of wide bandwidth, outstanding ac and dc performance, and a dual-path digital filter to give greater flexibility to designers of automated test equipment, medical imaging, scientific instrumentation, and test and measurement. The low latency filter path provides 24-bit settling as fast as 2.65 us, thereby lending itself to fast multiplexed applications. For complete product information, see: www.ti.com/ads1675-pr.

Key Features

    --  AC performance: 103 dB of dynamic range at 4 MSPS, 111 dB of dynamic
        range at 125 kSPS and -107 dB of total harmonic distortion
    --  DC accuracy: 3 ppm integral nonlinearity, 4 uV/C offset drift and 4
        ppm/C gain drift
    --  575 mW power consumption
    --  2.65 us latency for 24-bit settling accuracy
    --  Simple read-only serial interface with either standard CMOS or
        serialized LVDS

Key Benefits

    --  60 percent faster sampling rate and 3x faster settling time than the
        nearest competition
    --  Excellent ac performance and dc accuracy operating at speeds up to 4
        MSPS enables wide bandwidth conversions with high resolution
    --  User selectable dual-path digital filter allows customers to optimize
        between bandwidth and latency for optimal performance
    --  Easily connects to microcontrollers, DSPs or FPGAs
    --  Compatible devices to complete the signal chain, including OPA211 as
        reference driver, THS4503 as input driver and REF5030 as voltage
        reference

Availability and pricing

The ADS1675 is available now in a TQFP-64 package starting at $17.95 each in 1,000-piece quantities (suggested resale pricing). The easy-to-use evaluation modules (EVM) for this device will be available in Q2 2009.
