Octal, 13-Bit Voltage-Output DAC

with Parallel Interface

_________________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 鹵5V supply. Bipolar output voltages with up to 鹵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 (LD_ ) input transfers data from the

鈥撯€?/div>

鈥斺€?/div>

input latch to the DAC latch. The four LD_ inputs each control

two DACs, and all DAC latches can be updated simultane-

鈥撯€?/div>

鈥斺€?/div>

鈥撯€?/div>

鈥斺€?/div>

ously by asserting all LD_ pins. An asynchronous clear (CLR)

input resets the output of all eight DACs to AGND_. Asserting

CLR resets both the DAC and the input latch to bipolar zero

(1000hex). On power-up, reset circuitry performs the same

鈥撯€?/div>

鈥斺€?/div>

function as CLR. All logic inputs are TTL/CMOS compatible.

The MAX547 is available in 44-pin plastic quad flat pack

and 44-pin PLCC packages.
