Low-Power, 13-Bit Voltage-Output DACs
with Serial Interface
__________________General Description
The MAX535/MAX5351 combine a low-power, voltage-
output, 13-bit digital-to-analog converter (DAC) and a
precision output amplifier in an 8-pin µMAX or DIP pack-
age. The MAX535 operates from a single +5V supply
and the MAX5351 operates from a single +3.3V supply.
Both devices draw only 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 MAX535/MAX5351 ideal for a wide range of appli-
cations, including industrial process control. Other fea-
tures include a software shutdown and power-on reset.
The serial interface is compatible with either SPI™/
QSPI™ or Microwire™. 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 indepen-
dently or simultaneously with the input register. All logic
inputs are TTL/CMOS-logic compatible and buffered
with Schmitt triggers to allow direct interfacing to opto-
couplers.
