TI introduces industry’s fastest 24-bit delta-sigma ADC with speeds up to 4 MSPSPrecision ADC offers 60 percent faster sample rate than nearest competition

DALLAS (March 26, 2009) – 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 μs, 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 µV/C offset drift and 4 ppm/C gain drift

575 mW power consumption

2.65 μs 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.
