12-Bit Binary Multiplying D/A Converter
General Description
The DAC1218andthe DAC1219are 12-bit binary, 4-quad-
rant multiplyingDtoA converters.The linearity, differential
non-linearityand monotonicity specificationsfor these con-
vertersareall guaranteed over temperature.In addition,
these parametersare specifiedwith standard zeroandfull-
scale adjustment proceduresas opposedtothe impractical
bestfit straightline guarantee.
This levelof precisionis achieved thoughthe useofan
advanced silicon-chromium (SiCr) R-2R resistor laddernet-
work. This typeof thin-film resistor eliminatesthe parasitic
diode problems associated with diffused resistors andal-
lowsthe applied reference voltageto range from b25Vto
25V, independentofthe logic supply voltage.
CMOS current switches and drive circuitryare usedto
achievelow power consumption(20 mW typical)and mini-
mize output leakage current errors (10nA maximum).
Unique digital input circuitry maintainsTTL compatible input
threshold voltages overthefull operating supply voltage
range.
The DAC1218 and DAC1219are direct replacementsfor
the AD7541 series, AD7521 series,and AD7531 serieswith significant improvementinthe linearity specification.In
applications where direct interfaceoftheDtoA converterto microprocessor busis desirable, the DAC1208 and
DAC1230 series eliminatethe needfor additional interface
logic.
Features Linearity specified with zeroand full-scale adjust only Logic inputs which meet TTL voltage level specs (1.4V
logic threshold) Works with g10V referenceÐfull 4-quadrant
