Small footprint, RoHS compliant, 72-lead LFCSP 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
the ADL5370. …
