Overview
The AD9737ABBCZ is an 11-bit, 2.5 GSPS high-performance RF Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. This device is part of the AD9737A/AD9739A series, which are designed to synthesize wideband signals from dc up to 3 GHz. The AD9737A is pin and functionally compatible with the AD9739, except it does not support synchronization or RZ mode and operates between 1.6 GSPS and 2.5 GSPS. This design allows for system calibration by keeping nonideal artifacts such as images and discrete clock spurs stationary between power-up cycles.
