New 14-bit ADC from TI scales higher in bandwidth

Texas Instruments has released a new 14-bit 250 MSPS analog to digital converter IC ADS62P49. TI claims, ADS62P49 provides 66% greater bandwidth than competing dual ADCs.
The ADS62P49 achieves 73-dBFS signal-to-noise ratio (SNR) and 85-dBc spurious-free dynamic range (SFDR) at an input frequency of 60 MHz. ADS62P49 is suggested for telecom, defense, imaging, measuring instruments for its large signal bandwidth and sensitivity.

"Communications, defense and test design engineers are constantly challenged to create signal and data acquisition receivers with increasingly wide signal bandwidths that do not compromise overall system performance," said Art George, senior vice president of TI's High-Performance Analog business unit. "TI addresses these challenges with the ADS62P49 which delivers high-performance, compact, power-efficient designs and enables rapid deployment of 3G and 4G systems, software defined radios and spectrum analyzers."

Low power consumption of 625 mW per channel is another advantage of this converter.
Programmable gain and other user-selectable settings feature of this ADC allow designers to optimize SNR, SFDR and input swing based on the unique need of their applications.
