__________________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.
