MAX19693 - 12-Bit, 4.0Gsps, Wideband DAC Delivers Industry-Leading Dynamic Performance at Lowest Power

• The MAX19693 is a 12-bit, 4.0Gsps digital-to-analog converter (DAC) that is optimized for direct digital synthesis of high-frequency and wideband signals in the first Nyquist zone.
• This DAC offers excellent spurious and noise performance and can directly synthesize signals in the frequency range from DC to nearly 2GHz.
• The 4.0Gsps output-update rate and high-performance architecture of the DAC enable this excellent wideband dynamic performance.
• The MAX19693 is ideal for wideband communications, radar, arbitrary waveform generators, and direct digital synthesis (DDS).

SUNNYVALE, CA—April 3, 2008—Maxim Integrated Products (Pink Sheets: MXIM) introduces the MAX19693, the industry's highest performance 12-bit, 4.0Gsps, wideband digital-to-analog converter (DAC). This DAC is optimized for direct digital synthesis of high-frequency and wideband signals in the first Nyquist zone. It offers excellent spurious and noise performance and can directly synthesize signals in the frequency range from DC to nearly 2GHz. The MAX19693 achieves a spurious-free dynamic range (SFDR) of greater than 70dBc for output frequencies less than 800MHz, and 62dBc at an output frequency of 1500MHz. At a 4.0Gsps update rate and output frequency of 200MHz, the device offers a wideband-noise spectral density of -164dBm/Hz. The 4.0Gsps output-update rate and high-performance architecture of the DAC enable this excellent wideband dynamic performance. The MAX19693's outstanding performance makes it ideal for wideband communications, radar waveform and local oscillator (LO) signal synthesis, electronic warfare, arbitrary waveform generators, automatic test equipment, and direct digital synthesis (DDS).

The MAX19693 operates from 3.3V and 1.8V supplies, and consumes 1180mW at 4.0Gsps. Fully specified over the -40°C to +85°C extended temperature range, it is available in a compact, 11mm x 11mm, 169-ball CSBGA package. Contact the factory for pricing.
