The RDA012
is a high-performance 12-bit digital to analog converter (DAC)
with a data update rate of over 1GS/s. The RDA012 has been optimized for ultra high-speed applications, achieving
65dB of spurious free dynamic range (SFDR) at 1GS/s and fo of
333MHz. The DAC utilizes a segmented current source to reduce
glitch energy and to achieve high
linearity performance. For better dynamic performance, the
DAC outputs are internally
terminated with 50Ω resistance. It outputs a nominally full-scale
current of 12mA when terminated
with external 50Ω resistors.
