Texas Instruments ADS4149 14 bit 250MSPS Low Power ADC ADS4149IRGZ25

The ADS4149IRGZ25 is a 14-bit analog-to-digital converter (ADC) capable of sampling rates up to 250 MSPS. It operates with an ultralow power consumption of 265 mW at maximum sampling rate and 201 mW at 160 MSPS, utilizing a single 1.8V supply. The device features high dynamic performance with a signal-to-noise ratio (SNR) of 70.6 dBFS at 170 MHz and a spurious-free dynamic range (SFDR) of 84 dBc at the same frequency. The ADS4149IRGZ25 supports dynamic power scaling, allowing it to adjust power consumption based on the sample rate without sacrificing performance. It includes a double data rate (DDR) LVDS output interface with programmable swing options of 350 mV (standard) and 200 mV (low), as well as a parallel CMOS interface. The device also features programmable gain options up to 6 dB for optimizing SNR and SFDR trade-offs, along with DC offset correction capabilities. Packaged in a compact QFN-48 (7mm x 7mm) format, the ADS4149IRGZ25 is specified for operation over an industrial temperature range of -40¬8C to +85¬8C, making it suitable for a variety of applications, including multi-carrier and wide bandwidth communications.
