DescriptionThe AD7549AQ is one of the AD7549 series.The AD7549AQ is a monolithic dual,12-bit,current output D/A converter.It is packaged in both 0.3" wide 20-pin DIPs and in 20-terminal surface mount packages.Both DACs provide four quadrant multiplication capabilities with a sepatate reference input and feedback resistor for each DAC.The monolithic construction ensures excellent thermal tracking and gain error tracking between the two DACs.
Features of the AD7549AQ are:(1)two doubled buffered 12-bit DACs; (2)4-quadrant multiplication; (3)low gain error(3LSBs max); (4)DAC ladder resistance matching:1%; (5)space saving skinny DIP and surface mount packages ; (6)latch-up proof; (7)extended temperature range operation.
The absolute maximum ratings of the AD7549AQ can be summarized as:(1)Vdd to DGND:-0.3V,17V; (2)Vrefa,Vrfbb to AGND:±25V; (3)Vrfba,Vrfbb to AGND:±25V; (4)digital input voltage to DGND:-0.3V,Vdd+0.3V; (5)Iouta,Ioutb to DGND:-0.3V,Vdd+0.3V; (6)AGND to DGND:-0.3V,Vdd +0.3V; (7)power dissipation(any package):450mW(To+75);6mW/(derates above+75); (8)operating temperature range:-40 to 85(commercial plastic);-40 to 85(industrial hermetic);-55 to 125(extended hermetic);-65 to 150(storage temperature); (9)lead temperature:300.If you want to know more information such as the electrical characteristics, please download the datasheet in www.seekic.com or www.chinaicmart.com.
