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).
