Hot-selling and scarce MAX512CSD Low-Cost, Triple, 8-Bit Voltage-Output DACs with Serial Interface SOP14 spot stock

Product Descriptions

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 within0.5V 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 frequency 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 loaded independently or in parallel at the positive edge of –C^–.  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.​
