Single carrier W-CDMA ACLR = 80 dBc at 61.44 MHz IF
Innovative switching output stage permits usable outputs
beyond Nyquist frequency
LVDS inputs with dual-port or optional interleaved singleport operation
Differential analog current outputs are programmable from
8.6 mA to 31.7 mA full scale
Auxiliary 10-bit current DACs with source/sink capability for
external offset nulling
Internal 1.2 V precision reference voltage source
Operates from 1.8 V and 3.3 V supplies
315 mW power dissipation
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. …
