DESCRIPTION
Multiplication
The DAC0830 is an advanced CMOS/Si-Cr 8-bit
• Can Be Used in the Voltage Switching Mode
multiplying DAC designed to interface directly with the
8080, 8048, 8085, Z80
®
, and other popular
• Logic Inputs Which Meet TTL Voltage Level
microprocessors. A deposited silicon-chromium R-2R
Specs (1.4V Logic Threshold)
resistor ladder network divides the reference current
• Operates “STAND ALONE” (without μP) if
and provides the circuit with excellent temperature
Desired
tracking characteristics (0.05% of Full Scale Range
maximum linearity error over temperature). The circuit
• Available in 20-Pin SOIC or PLCC Package
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.
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).
