Dual, 8-Bit, Voltage-Output Serial DAC in 8-Pin SO Package
_______________General DescriptionThe MAX522 contains two 8-bit, buffered, voltage-output
digital-to-analog converters (DAC A and DAC B) in small
8-pin SO and DIP packages. DAC A’s buffer can source
and sink 5mA, and DAC B’s output can source and sink
500µA, both to within 0.5V of ground and VDD. The
MAX522 operates with a single +2.7V to +5.5V supply.
The device utilizes a 3-wire serial interface, which oper-
ates at clock rates up to 5MHz and is compatible with
SPI™, QSPI™, and Microwire™ interface standards.
The serial input shift register is 16 bits long and con-
sists of eight bits of DAC input data and eight bits for
DAC selection and shutdown control. DAC registers
can be loaded independently or in parallel at the posi-
tive edge of CS.
The MAX522’s ultra-low power consumption and small
8-pin SO package make it ideal for portable and bat-
tery-powered applications. Supply current is less than
1mA and drops below 1µA in shutdown mode. In addi-
tion, the reference input is disconnected from the REF
pin during shutdown, further reducing the system’s total
power consumption. The software format is compatible
with the MAX512/MAX513 triple 8-bit DACs.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS(VDD= +2.7V to +5.5V, REF = VDD, TA= TMINto TMAX, unless otherwise noted. Typical values are at TA= +25°C.)
Note 1:The outputs may be shorted to VDDor GND if the package power dissipation is not exceeded. Typical short-circuit current 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.

Note 2:Reduced digital code range (code 24 through code 232) is due to swing limitations of the output amplifiers. See Typical
Operating Characteristics.
Note 3:Reference input resistance is code dependent. The lowest input resistance occurs at code 55hex. Refer to the Reference
Inputsection in the Detailed Description.
Note 4:Guaranteed by design. Not production tested.
Note 5:Input capacitance is code dependent. The highest capacitance occurs at code 00hex.
