DAC1405D750 Description
The DAC1405D750 is a high-speed 14-bit dual channel Digital-to-Analog Converter (DAC) with selectable 4× or 8× interpolating filters optimized for multi-carrier wireless transmitters. Thanks to its digital on-chip modulation, the DAC1405D750 allows the plex I and Q inputs to be converted from BaseBand (BB) to IF. The mixing frequency is adjusted via a Serial Peripheral Interface (SPI) with a 32-bit Numerically...
