Low-Power, Quad, 12-Bit Voltage-Output DAC

with Serial Interface

__________________General Description

The MAX525 combines four low-power, voltage-output,

12-bit digital-to-analog converters (DACs) and four pre-

cision output amplifiers in a space-saving, 20-pin pack-

age. In addition to the four voltage outputs, each

amplifier’s negative input is also available to the user.

This facilitates specific gain configurations, remote

sensing, and high output drive capacity, making the

MAX525 ideal for industrial-process-control applica-

tions. Other features include software shutdown, hard-

ware shutdown lockout, an active-low reset which clears

all registers and DACs to zero, a user-programmable

logic output, and a serial-data output.

Each DAC has a double-buffered input organized as an

input register followed by a DAC register. A 16-bit serial

word loads data into each input/DAC register. The serial

interface is compatible with SPI™/QSPI™ and

MICROWIRE™. It allows the input and DAC registers to

be updated independently or simultaneously with a sin-

gle software command. The DAC registers can be

simultaneously updated through the 3-wire serial inter-

face. All logic inputs are TTL/CMOS-logic compatible.
