Product Description
The RDA012M4 is a digital-to-analog converter
(DAC) with a 4:1 input multiplexer and a
maximum update rate of 1.3GS/s. The
integrated DAC utilizes a segmented current
source to reduce the glitch energy and to
achieve high linearity performance. For best
dynamic performance, the DAC outputs are
internally terminated with 50Ω resistance, and
outputs a nominal full-scale current of 12mA
when terminated with external 50Ω resistors. For
a convenient interface with most CMOS ICs, the
digital data inputs are low voltage NMOS
compatible.

1
Sample tested at T
A
= 25C unless other temperature is specified
Guaranteed by design and/or characterization testing
All tests are continuous, not pulsed. Therefore, Tj (junction temperature) > Tc (case temperature) > Ta (ambient temperature).
This is the normal operating condition and is more stressful than a pulsed test condition.
The tests are conducted with the power set to VCC
MIN
and to VCC
MAX
.
