AD7542JN

The AD7542JN is designed as one kind of precision 12-bit CMOS multiplying DAC designed for direct interface to 4- or 8-bit microprocessors.It consists of three 4-bit data registers,a 12-bit DAC register,address decoding logic and a 12-bit CMOS multiplying DAC.Data is loaded into the data registers in three 4-bit bytes and subsequently transferred to the 12-bit DAC register.All data loading or data transfer operations are identical to the write cycle of a static RAM.

Features of the AD7542JN are:(1)resolution:12 bits;(2)nonlinearity:+/-1/2LSB Tmin to Tmax;(3)low gain drift:2ppm/ typ,5ppm/ max;(4)microprocessor compatible;(5)full 4-quadrant multiplication;(6)fast interface timing;(7)low power dissipation:40 mW max;(8)low cost;(9)small size:16-pin DIP and 20-terminal surface mount package.

The absolute maximum ratings of the AD7542JN can be summarized as:(1)VDD to AGND:VAGND to DGND:0V to +7V;(2)Vdd to DGND:0V to +7V;(3)AGND to DGND:Vdd+0.3 V;(4)DGND to AGND:Vdd+0.3 V;(5)storage temperature range:-65 to +150;(6)lead temperature(soldering 10 sec):+300;(7)power dissipation(any package) to +75:450 mW;(8)derates above +75 by:10 mW/;(9)digital inputs to GND:-0.3V to Vdd+0.3 V.If you want to know more information such as the electrical characteristics about the AD7542JN,please download the datasheet in www.seekic.com or www.chinaicmart.com .
