GENERAL DESCRIPTION
The AD9780/AD9781/AD9783 include pin-compatible, high
dynamic range, dual digital-to-analog converters (DACs) with
12-/14-/16-bit resolutions, and sample rates of up to 500 MSPS.
The devices include specific features for direct conversion transmit
applications, including gain and offset compensation, and they
interface seamlessly with analog quadrature modulators such as
A proprietary, dynamic output architecture permits synthesis
of analog outputs even above Nyquist by shifting energy away
from the fundamental and into the image frequency.
Full programmability is provided through a serial peripheral
interface (SPI) port. Some pin-programmable features are also
offered for those applications without a controller.
PRODUCT HIGHLIGHTS
1.
Low noise and intermodulation distortion (IMD) enable
high quality synthesis of wideband signals.
2.
Proprietary switching output for enhanced dynamic
performance.
3.
Programmable current outputs and dual auxiliary DACs
provide flexibility and system enhancements.
