DAC34SH84IZAYR Datasheet PDF - TI

●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. A high-performance

●low-jitter clock multiplier simplifies clocking of the device without significant impact on the dynamic

●range. The digital quadrature modulator correction (QMC) enables complete IQ compensation for gain,

●offset and phase between channels in direct upconversion applications.
