TI Unites Speed and Efficiency with Industry's Fastest Dual, 14-bit ADC


New 250-MSPS data converter provides 66 percent greater bandwidth than competing dual ADCs

Texas Instruments Incorporated introduced a dual, 14-bit analog-to-digital converter (ADC) at 250 MSPS (mega samples per second) to deliver a premier combination of wide signal bandwidth, high dynamic performance and low power consumption. 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. With the industry's fastest sample rate, the ADS62P49 provides increased signal bandwidth without compromising range and sensitivity in communications and defense imaging systems or accuracy in wide-band test and measurement equipment.

"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."

Key features and benefits of the ADS62P49
  • Fastest dual, 14-bit ADC at 250 MSPS enables multi-channel, wide-bandwidth sampling without sacrificing dynamic performance, for enhanced accuracy in portable test equipment
  • Low power of 625 mW per channel reduces thermal footprint for increased system efficiency in high-density, multi-antenna base station receivers and software defined radios
  • Programmable gain and other user-selectable settings maximize design flexibility. Internal gain up to 6 dB in 1-dB steps allows customers to optimize SNR, SFDR and input swing based on the unique need of their applications. Designers can maximize SNR to enhance linearization effectiveness in digital pre-distortion (DPD) solutions, while SFDR can be increased and input drive reduced to improve small-signal analysis in defense and radio receiver applications
  • Complete signal chain with comprehensive evaluation tools suite speeds time to market. Complementary products include: DACs (DAC5682Z, DAC5688), amplifiers (THS4509), RF components (TRF3703, TRF3761), DPD transmit processors (GC5325), clock distribution circuits (CDCE72010) and digital signal processors (TMS320C6727B)
  • First in a series of four 12- and 14-bit dual channel ADCs with sample rates of 210 and 250 MSPS (ADS62P28, ADS62P29, ADS62P48). Pin-compatible to dual-channel ADS6000 family for easy upgrades in speed and resolution
