PRODUCT DESCRIPTION  
PIN CONFIGURATIONS  
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 internal voltage reference insures that the analog input is  
biased to midscale with low offset when driven from an ac-  
coupled source. In dc-coupled applications, the midscale voltage  
reference can be used to control external biasing amplifiers to  
minimize offsets due to variations in temperature or supply voltage.
