GENERAL DESCRIPTION

The AD9148 is a quad, 16-bit, high dynamic range, digital-toanalog converter (DAC) that provides a sample rate of 1000 MSPS. This device includes features optimized for direct conversion transmit applications, including gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators such as the ADL5371/ADL5372/ADL5373/ADL5374/ADL5375.
