DAC1218/DAC1219  
12-Bit Binary Multiplying D/A Converter  
General Description  
The DAC1218 and the DAC1219 are 12-bit binary, 4-quad-  
rant multiplying D to A converters. The linearity, differential  
non-linearity and monotonicity specifications for these con-  
verters are all guaranteed over temperature. In addition,  
these parameters are specified with standard zero and full-  
scale adjustment procedures as opposed to the impractical  
best fit straight line guarantee.  
a microprocessor bus is desirable, the DAC1208 and  
DAC1230 series eliminate the need for additional interface  
logic.  
Features

Linearity specified with zero and full-scale adjust only

Logic inputs which meet TTL voltage level specs (1.4V  
logic threshold)  
This level of precision is achieved though the use of an  
advanced silicon-chromium (SiCr) R-2R resistor ladder net-  
work. This type of thin-film resistor eliminates the parasitic  
diode problems associated with diffused resistors and al-  
b
lows the applied reference voltage to range from 25V to  
25V, independent of the logic supply voltage.

All parts guaranteed 12-bit monotonic  
CMOS current switches and drive circuitry are used to  
achieve low power consumption (20 mW typical) and mini-  
mize output leakage current errors (10 nA maximum).  
Unique digital input circuitry maintains TTL compatible input  
threshold voltages over the full operating supply voltage  
range.

The DAC1218 and DAC1219 are direct replacements for  
the AD7541 series, AD7521 series, and AD7531 series with  
a significant improvement in the linearity specification. In
