DAC34H84IZAYR

四通道， 16位， 1.25 GSPS数位类比转换器（ DAC ） Quad-Channel, 16-Bit, 1.25 GSPS Digital-to-Analog Converter DAC

Description

The DAC34H84 is a very low power, high dynamic range, quad-channel, 16-bit digital-to-analog converter DAC with a sample rate as high as 1.25 GSPS.

The device includes features that simplify the design of complex transmit architectures: 2x to 16x 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.
