The AD9066 is a dual 6-bit ADC that has been optimized for low-cost in-phase and quadrature (I and Q) demodulators. Primary applications include digital direct broadcast satellite applications where broadband quadrature phase shift keying (QPSK) modulation is used. The AD9066 provides an internal voltage reference and operates from a single +5 volt power supply to reduce total system cost and power dissipation.
