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. In these receivers the recovered signal is separated into I and Q vector components and digitized. To reduce total system cost and power dissipation, the AD9066 provides an internal voltage reference and operates from a single +5 volt power supply. Digital outputs are CMOS com- patible and rated to 60 MSPS conversion rates. The digital input (ENCODE) utilizes a CMOS input stage with a TTL compatible (1.4 V) threshold. The AD9066 is housed in a 28-lead SOIC and a 28-lead SSOP package and is available in two temperature grades. The AD9066JR is rated for operation over the 0°C to 70°C commer- cial temperature range. The AD9066AR/ARS is rated for the –40°C to +85°C industrial temperature range.
The AD9066 is a dual-channel analog-to-digital converter designed specifically for low-cost in-phase (I) and quadrature (Q) demodulators. It features two matched 6-bit ADCs on a single chip, providing digital outputs that are CMOS compatible. The device operates from a single +5 volt power supply and includes an internal voltage reference to bias the analog input to midscale for AC-coupled applications.
