Octal, 13-Bit Voltage-Output DAC
with Parallel Interface
_________________General Description _____________________________Features
The MAX547 contains eight 13-bit, voltage-output digital-to-
analog converters (DACs). On-chip precision output ampli-
fiers provide the voltage outputs. The MAX547 operates
from a ±5V supply. Bipolar output voltages with up to ±4.5V
voltage swing can be achieved with no external compo-

o Calibrated Linearity
nents. The MAX547 has four separate reference inputs;
each is connected to two DACs, providing different full-
scale output voltages for every DAC pair.
The MAX547 features double-buffered interface logic with a
13-bit parallel data bus. Each DAC has an input latch and a
DAC latch. Data in the DAC latch sets the output voltage. The
