TI Introduces 14-bit, 170MSPS Analog-to-Digital Converter for Wideband Signal Processing Applications

ADC Offers Highest Dynamic Performance (SNR/SFDR) at Highest Speed

Sep 26, 2005

DALLAS (September 26, 2005) - Extending its family of leading-edge, high-speed data converters, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced another technology advancement with a 14-bit, 170MSPS (mega samples per second) analog-to-digital converter (ADC) featuring unmatched dynamic performance. The ADS5545 offers 72dBFS signal-to-noise ratio (SNR) and 84dBc spurious-free dynamic range (SFDR) at the maximum sample rate of 170MSPS and an input frequency of 150MHz, providing increased system capabilities in advanced communications, instrumentation, test and measurement, medical, video and imaging applications.

"The ADS5545 builds upon the leadership performance of the ADS5500 14-bit, 125MSPS ADC by offering best-in-class performance in a 7mm x 7mm QFN package with only 1W core power dissipation," said Roberto Sadkowski, business unit manager for TI's high-speed ADCs. "This new device enables a wide range of benefits such as improved receiver capabilities in wireless communications, higher quality imaging in video systems and extended signal analysis for test equipment."
The device includes an internal sample and hold, low-jitter clock buffer, internal reference, and options for parallel CMOS or LVDS outputs. It operates from a single 3.3V supply and is specified over the industrial temperature range of -40C to +85C.
TI provides customers a state-of-the-art signal chain for wideband applications with high-speed amplifiers (THS4509, OPA847), high-speed digital-to-analog converters (DAC5687), digital up/down converters (GC5016), crest factor reduction processors (GC1115) and quadrature modulators (TRF3701, TRF3702). The ADS5545 is also optimized to work with TI's high-performance TMS320C6xTM DSP platform.

Availability and Packaging

The ADS5545 is sampling now, with volume production scheduled for 2Q 2006. The device comes in a 48-pin QFN package (7mm x 7mm) and is priced at $62.50 in 1,000 piece quantities (suggested resale pricing). Evaluation modules (EVMs) are also available.
