_________________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

–

—

–

inputs each control

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

ously by asserting all

–

—

–

pins. An asynchronous clear (

)

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

–

resets both the DAC and the input latch to bipolar zero

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

function as

. All logic inputs are TTL/CMOS compatible.

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

and 44-pin PLCC packages.

Note 1: PSRR is tested by changing the respective supply voltage by ±5%.

Note 2: For best performance, REF_ should be greater than AGND_ + 2V and less than V

- 0.6V. The device operates with

reference inputs outside this range, but performance may degrade. For further information on the reference, see the

Reference and Analog-Ground Inputs

section in the

Detailed Description

Note 3: Reference input resistance is code dependent. See

Description

Note 4: Typical settling time with 1000pF capacitive load is 10µs.

Note 5: Guaranteed by design. Not production tested.

Note 6: Guaranteed by supply-rejection test.
