The MAX5304 combines a low-power, voltage-output,
10-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
sensing, and high output-current capability. This makes
the MAX5304 ideal for a wide range of applications,
including industrial process control. Other features
include a software shutdown and power-on reset.
The serial interface is SPI?/QSPI?/MICROWIRE?
compatible. 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 register can be updated independently or
simultaneously with the input register. All logic inputs
are TTL/CMOS-logic compatible and buffered with
Schmitt triggers to allow direct interfacing to optocouplers.
