TI claims fastest dual 14-bit ADC

Dallas, Tex.—Texas Instruments Inc. has developed a dual, 14-bit analog-to-digital converter (ADC) that it says delivers that industry's fastest sample rate at 250 MSPS (mega samples per second).

Dubbed ADS62P49, TI's latest 14-bit ADC achieves 73-dBFS signal-to-noise ratio (SNR) and 85-dBc spurious-free dynamic range (SFDR) at an input frequency of 60 MHz. TI says it 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 ADS62P4 achieves low power of 625 mW per channel, reducing the thermal footprint for increased system efficiency in high-density, multi-antenna base station receivers and software defined radios.

It also features programmable gain and other user-selectable settings to 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

Pricing: $144.75 in 1,000-piece quantities.
Availability: Today in a 9 mm x 9mm QFN package.
