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

+3V (MAX513) Supply, or from Bipolar Supplies

0.5V of V or V . The buffer for DAC B can source or

s ink 0.5mA to within 0.5V of V

unbuffered, providing a third voltage output with increased

+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

(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.
