GENERAL DESCRIPTION
compatible, high dynamic range, dual digital-to-analog
converters (DACs) with 8-/10-/12-/ 14-/16-bit resolutions
and sample rates of up to 250 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 the
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. In addition, some pin-programmable
features are offered for those applications without a controller.
PRODUCT HIGHLIGHTS
1. Low noise and intermodulation distortion (IMD) enables
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.
