AD9767

The AD9767 is a dual-channel, 14-bit, 125 MSPS digital-to-analog converter from ADI, part of the TxDAC family, that provides two matched current-output channels in one package for a transmit or an arbitrary-waveform path. Each channel has an independent on-chip reference and a gain control, so a designer can set the full-scale current and the offset for a matched or a deliberately different pair of outputs. The part uses a segmented current-steering architecture that gives a high spurious-free dynamic range and a low intermodulation distortion, which a communications or an instrumentation transmitter needs to keep the adjacent channel clean, and the dual channels are matched in delay so a quadrature or an I/Q pair stays aligned. The outputs are a differential current that a transformer or a differential amplifier converts to a voltage, and the data is loaded through a parallel interface with a latch or an interleaved mode. The part runs from a single 3.3 V or a 5 V supply with a low power consumption for the update rate, and it includes a power-down mode for a system that must save power between bursts. Typical applications include a communications transmitter, a direct digital synthesis or an arbitrary waveform generator, an instrumentation signal source and a medical or an imaging waveform path. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the output network and the update mode and plan the layout.
