DAC1658D
High-performance 16-bit Dual DAC, High Common Mode
The DAC1658D1G5 is a high-speed high-performance 16-bit dual channel Digital-to-Analog Converter (DAC). The device provides sample rates up to 1.5 Gsps with selectable 2x, 4x and 8x interpolation filters optimized for multi carrier and broadband wireless transmitters. The DAC165xD1G5 integrates a JEDEC JESD204B compliant high-speed serial input data interface running up to 10 Gbps allowing dual channel input sampling at up to 750 Msps over four differential lanes. It offers numerous advantages over traditional parallel digital interfaces.
