DAC34SH84IZAYR

四通道， 16位， 1.5 GSPS数位类比转换器（ DAC ） Quad-Channel, 16-Bit, 1.5 GSPS Digital-to-Analog Converter DAC

DESCRIPON

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.
