_________________General Description
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-
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
eight input latches are addressed with three address lines.
Data is loaded to the input latch with a single write instruction.
An asynchronous load (

) input transfers data from the
input latch to the DAC latch. The four

ously by asserting all

pins. An asynchronous clear (

resets both the DAC and the input latch to bipolar zero
(1000hex). On power-up, reset circuitry performs the same

. All logic inputs are TTL/CMOS compatible.
The MAX547 is available in 44-pin plastic quad flat pack
and 44-pin PLCC packages.
