TI Introduces 13-Bit, 250MSPS Analog-to-Digital Converter With Best-in-Class Dynamic Performance

Posted on: Tuesday, 23 August 2005, 09:00 CDT

DALLAS, Aug. 23 /PRNewswire/ -- Texas Instruments Incorporated (TI) today announced a 13-bit, 250MSPS analog-to-digital converter (ADC) which features best-in-class dynamic performance at high input frequencies. The ADS5444 offers 68dB signal-to-noise ratio (SNR) and 75dB spurious-free dynamic range (SFDR) at the maximum sample rate of 250MSPS and an input frequency of 230MHz, making it ideal for a variety of wideband applications including software-defined radios, base station receivers, and test and measurement systems. (See http://www.ti.com/ads5444-pr .)

The ADS5444 provides a complete solution by including a high-bandwidth input buffer, a linear track-and-hold stage and an internal reference, simplifying system design requirements. The ADC operates from a 5V supply, while providing LVDS-compatible digital outputs from a 3.3V supply. The device is specified over the industrial temperature range of -40C to +85C.

"The ADS5444 successfully extends the industry-leading SNR and SFDR performance achieved by the recently announced ADS5440 13-bit, 210MSPS ADC to even higher sample rates," said Roberto Sadkowski, business unit manager for TI's high-speed ADCs.

The ADS5444 is optimized to work with TI's high-performance TMS320C6x(TM) DSP platform. TI also has a range of high-speed amplifiers, such as the THS4509 and OPA847, and digital-to-analog converters, such as the DAC5687, which are well suited to work with the ADS5444 to provide a truly state-of- the-art signal chain for wideband applications.

Availability and Packaging

The ADS5444 is sampling now, with volume production scheduled for 4Q 2005. The device comes in an 80-pin TQFP PowerPad(TM) package and is priced at $95.00 in 1,000 piece quantities (suggested resale pricing). Evaluation modules (EVMs) are also available.

TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, an online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.
