AD9772AASTZ

GENERAL DESCRIPTION

The AD9772A is a single-supply, oversampling, 14-bit digital to-analog converter (DAC) optimized for baseband or IF waveform reconstruction applications requiring exceptional dynamic range. Manufactured on an advanced CMOS process, it integrates a complete, low distortion 14-bit DAC with a 2× digital interpolation filter and clock multiplier. The on-chip PLL clock multiplier provides all the necessary clocks for the digital filter and the 14-bit DAC. A flexible differential clock input
allows for a single-ended or differential clock driver for optimum jitter performance.
