Texas Instruments Inc. (TI) has launched ADS62P49—a dual, 14-bit analog-to-digital converter (ADC) that features 250MSPS (mega samples per second) and achieves 73dBFS signal-to-noise ratio (SNR) and 85dBc spurious-free dynamic range (SFDR) at an input frequency of 60MHz. 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.
The ADS62P49 features low power of 625mW per channel—reducing thermal footprint for increased system efficiency in high-density, multi-antenna base station receivers and software defined radios. The device also has programmable gain and other user-selectable settings, maximizing design flexibility. Internal gain up to 6dB 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. The ADS62P49 is available today in a 9x9mm QFN package.
