DAC0830/DAC0832  
8-Bit µP Compatible, Double-Buffered D to A Converters  
General Description  
Features  
n Double-buffered, single-buffered or flow-through digital  
data inputs  
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 cir-  
cuit uses CMOS current switches and control logic to  
achieve low power consumption and low output leakage  
current errors. Special circuitry provides TTL logic input volt-  
age level compatibility.  
n Easy interchange and pin-compatible with 12-bit  
DAC1230 series  
n Direct interface to all popular microprocessors  
n Linearity specified with zero and full scale adjust  
onlyNOT BEST STRAIGHT LINE FIT.  
±
n Works with 10V reference-full 4-quadrant multiplication  
n Can be used in the voltage switching mode  
n Logic inputs which meet TTL voltage level specs (1.4V  
logic threshold)  
n Operates “STAND ALONE” (without µP) if desired  
n Available in 20-pin small-outline or molded chip carrier  
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  
Key Specifications  
n Current settling time: 1 µs  
microprocessor-compatible DACs (MICRO-DAC ).  
n Resolution: 8 bits  
n Linearity: 8, 9, or 10 bits (guaranteed over temp.)  
n Gain Tempco: 0.0002% FS/˚C  
n Low power dissipation: 20 mW  
n Single power supply: 5 to 15 VDC  
Typical Application
