12-Bit, Low Cost, Monolithic D/A Converters  
Features  
Description  
• DAC 80V/DAC 85V Alternative Source  
• Monolithic Construction  
The Hl-DAC80V is a monolithic direct replacement for the  
popular DAC80 and AD DAC80. The HI-DAC85V is a mono-  
lithic direct replacement for the popular DAC85 and AD  
• Fast Settling Time (Typ) . . . . . . . . . . . . . . . . . . . . 1.5µs  
• Guaranteed Monotonicity  
DAC85 as well as the HI-5685V. Single chip construction  
along with several design innovations make the Hl-DAC80V  
the optimum choice for low cost, high reliability applications.  
Intersil’ unique Dielectric Isolation (Dl) processing reduces  
internal parasitics resulting in fast switching times and mini-  
mum glitch. On board span resistors are provided for good  
tracking over temperature, and are laser trimmed to high  
accuracy.  
• Wafer Laser Trimmed Linearity, Gain, Offset  
• Span Resistors On-Chip  
• On-Board Reference  
• Supply Operation. . . . . . . . . . . . . . . . . . . . . . . . . . ±12V  
Applications  
Internally the Hl-DAC80V/HI-DAC85V eliminates code  
dependent ground currents by routing current from the posi-  
tive supply to the internal ground node, as determined by an  
auxiliary R2R ladder. This results in a cancellation of code  
dependent ground currents allowing virtually zero variation  
in current through the package common, pin 21.  
• High Speed A/D Converters  
• Precision Instrumentation  
• CRT Display Generation

guaranteed over the -25 C to 85 C temperature range. It  
includes a buried zener reference featuring a low temperature  
coefficient as well as an on board operational amplifier. The  
Hl-DAC80V requires only two power supplies and will operate  
in the range of ± (11.4V to 16.5V).
