    TI introduces lowest power 250-MSPS, 14-bit ADC

      At a maximum sample rate of 250 mega samples per second (MSPS), the 14-bit TI ADS4149 is said to consume 30 percent less power while delivering 3-dB greater signal-to-noise ratio (SNR) than the nearest low-power ADC. TI claims ADS4149 consumes as little as 275 mW per channel at 250 MSPS and offers 72.5-dB SNR at 100-MHz input frequency. The first introduction in what is said to be a new class of high-speed analog-to-digital converters (ADCs) the ADS4149 family includes pin-compatible 12- and 14-bit options at 160 and 250 MSPS and buffered devices to enable designers to move to lower resolution and sample rates without altering their core design. The ADCs are targeted at defense, test and measurement, software defined radio and other communications applications. The ADS4149 is available in a 48-pin QFN package and is priced at $89 in 1,000-unit quantities.
