12-bit wideband D/A converter synthesizes signals from DC to 2-GHz

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX19693, a 12-bit, 4.0-Gsps, wideband D/A converter that is optimized for direct digital synthesis of high-frequency and wideband signals in the first Nyquist zone.

It can directly synthesize signals in the frequency range from DC to nearly 2-GHz. The MAX19693 achieves a spurious-free dynamic range (SFDR) of greater than 70dBc for output frequencies less than 800-MHz, and 62-dBc at an output frequency of 1500-MHz. At a 4.0-Gsps update rate and output frequency of 200-MHz, the device offers a wideband-noise spectral density of -164-dBm/Hz.

Applications include 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 3.3-V and 1.8-V supplies, and consumes 1180-mW at 4.0-Gsps. 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.
