12-Bit DAC Delivers 4 Gsamples/s

Dubbed the market's highest performance, 12-bit 4-Gsample/s DAC, the MAX19693 performs direct digital synthesis of high frequency and wideband signals in the first Nyquist zone. It can directly synthesize signals from dc to nearly 2 GHz and specifies a SFDR of greater than 70 dBc for output frequencies less than 800 MHz and 62 dBc at an output of 1.5 GHz. With a 4 Gsample/s update rate and output frequency of 200 MHz, the device exhibits a wideband-noise spectral density of -164 dBm/Hz. In a 169-ball CSBGA package, the MAX19693 operates from 3.3V and 1.8V supplies and consumes 1.18 W at the maximum sampling rate. For pricing, call MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA.
