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 s i n k 0.5mA to within 0.5V of V D D o r V S S . DAC C is unbuffered, providing a third voltage output with increased a c c u r a c y . 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 frequency of 5MHz and is compatible with SPITM, QSPITM, and MicrowireTM. 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 loa ed independently or in parallel at the positive edge d -- of CS. A latched logic output is also available for auxiliary control. Ultra-low power consumption and small packages (14-pin DIP/SO) make the MAX512/MAX513 ideal for portable and battery-powered applications. Supply current 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 system power consumption.

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: Digital code from 24 through 232 are due to swing limitations of output amplifiers on DAC A and DAC B. See Typical Operating Characteristics. Note 3: Reference input resistance is code dependent. The lowest input resistance occurs at code 55hex. Refer to the reference input section 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. Note 6: For single-supply mode, tie VSS to GND.
