__________________General Description

The MAX5302 combines a low-power, voltage-output,

12-bit digital-to-analog converter (DAC) and a precision

output amplifier in an 8-pin µMAX package. It operates

from a single +5V supply, drawing less than 280µA of

supply current.

The output amplifier’s inverting input is available to the

user, allowing specific gain configurations, remote sens-

ing, and high output current capability. This makes the

MAX5302 ideal for a wide range of applications, includ-

ing industrial process control. Other features include a

software shutdown and power-on reset.

The serial interface is SPI™/QSPI™/MICROWIRE™ com-

patible. The DAC has a double-buffered input, organized

as an input register followed by a DAC register. A 16-bit

serial word loads data into the input register. The DAC

with the input register. All logic inputs are TTL/CMOS-

logic compatible and buffered with Schmitt triggers to

allow direct interfacing to optocouplers.
