Low-Cost, Triple, 8-Bit Voltage-Output DACs
with Serial Interface
_______________General Description
The MAX512/MAX513 contain three 8-bit, voltage-output
digital-to-analog converters (DAC A, DAC B, and DAC C).
Output buffer amplifiers for DACs A and B provide voltage
outputs while reducing external component count. The
output buffer for DAC A can source or sink 5mA to within
0.5V of VDD or VSS. The buffer for DAC B can source or
sink 0.5mA to within 0.5V of VDD or VSS. DAC C is
unbuffered, providing a third voltage output with increased
accuracy. The MAX512 operates with a single
+5V ±10% supply, and the MAX513 operates with a
+2.7V to +3.6V supply. Both devices can also operate
with split supplies.
The 3-wire serial interface has a maximum operating fre-
quency of 5MHz and is compatible with SPI™, QSPI™,
and Microwire™. The serial input shift register is 16 bits
long and consists of 8 bits of DAC input data and 8 bits
for DAC selection and shutdown. DAC registers can be
loofaC–d—Se–.d
independently or in parallel at the positive
A latched logic output is also available for
edge
auxil-
iary control.
Ultra-low power consumption and small packages
(14-pin DIP/SO) make the MAX512/MAX513 ideal for
portable and battery-powered applications. Supply cur-
rent is only 1mA, dropping to less than 1µA in shutdown.
Any of the three DACs can be independently shut down.
In shutdown mode, the DAC's R-2R ladder network is
disconnected from the reference input, minimizing sys-
tem power consumption.

Note 1: The outputs may be shorted to VDD, VSS, or GND if the package power dissipation is not exceeded. Typical short-circuit cur-
rent to GND is 50mA.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
