DESCRIPTION  
The DAC0830 is an advanced CMOS/Si-Cr 8-bit  
multiplying DAC designed to interface directly with the  
8080, 8048, 8085, Z80®, and other popular  
microprocessors. A deposited silicon-chromium R-2R  
resistor ladder network divides the reference current  
and provides the circuit with excellent temperature  
tracking characteristics (0.05% of Full Scale Range  
maximum linearity error over temperature). The circuit  
uses CMOS current switches and control logic to  
achieve low power consumption and low output  
leakage current errors. Special circuitry provides TTL  
logic input voltage level compatibility.  
Can Be Used in the Voltage Switching Mode  
Logic Inputs Which Meet TTL Voltage Level  
Specs (1.4V Logic Threshold)  
Operates “STAND ALONE” (without μP) if  
Desired  
Available in 20-Pin SOIC or PLCC Package  
Double buffering allows these DACs to output a  
voltage corresponding to one digital word while  
holding the next digital word. This permits the  
simultaneous updating of any number of DACs.  
The DAC0830 series are the 8-bit members of a  
family of microprocessor-compatible DACs (MICRO-  
DAC).
