3 Description
The DAC34SH84 is a very low-power, high-dynamic
range, quad-channel, 16-bit digital-to-analog
converter (DAC) with a sample rate as high as
1.5 GSPS.
The device includes features that simplify the design
of complex transmit architectures: 2× to 16× digital
interpolation filters with over 90 dB of stop-band
attenuation simplify the data interface and
reconstruction filters. Independent complex mixers
allow flexible carrier placement.
