__________________General Desc ription
The +3V MAX5251 combines four low-power, voltage-
output, 10-bit digital-to-analog converters (DACs) and
four precision output amplifiers in a space-saving, 20-
pin package. 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
MAX5251 ideal for industrial-process-control applica-
tions. Other features include software shutdown, hard-
ware shutdown lockout, an active-low reset that 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
3-wire 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. All logic inputs are TTL/CMOS-
logic compatible.
