Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
It offers excellent spurious and noise performance and can directly synthesise 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 4.0Gsample/s update rate and output frequency of 200MHz, the device offers a wideband-noise spectral density of -164dBm/Hz.
The 4.0Gsample/s 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 3.3 and 1.8V supplies, and consumes 1180mW at 4.0Gsample/s.
Fully specified over the -40 to +85C extended temperature range, it is available in a compact, 11 x 11mm, 169-ball CSBGA package.
