DESCRIPTION
The DAC3152/DAC3162 is a low-power, low-latency,
high-dynamic-range, dual-channel, 10-/12-bit, pin-
compatible family of digital-to-analog converters
(DACs) with a sample rate as high as 500 MSPS.
The device simplicity (no software required), low
latency, and low power simplify the design of complex
systems. The DACs interface seamlessly with the
high-performance TRF370333 analog quadrature
modulator for direct upconversion architectures.
Digital data for both DAC channels is interleaved
through a single LVDS data bus with on-chip
termination. The high input rate of the devices allows
the processing of wide-bandwidth signals.
The devices are characterized for operation over the
entire industrial temperature range of –40°C to 85°C
and are available in a small 48-pin 7-mm × 7-mm
QFN package.
The low power, small size, speed, superior crosstalk,
simplicity, and low latency of the DAC3152/DAC3162
make them an attractive fit for a variety of
applications.
