MAX512
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 ponent count. The output buffer for DAC A can source or sink 5m A to within 0.5V of VDD or VSS. The buffer for DAC B can source or sink 0.5m A to within 0.5V of V DD or V SS . 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 frequency of 5MHz and is patible 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 loaded
