EVALUATION KIT AVAILABLE MAX5214/MAX5216 14-/16-Bit, Low-Power, Buffered Output, Rail-to-Rail DACs with SPI Interface General Description Features The MAX5214/MAX5216 are pin-compatible, 14-bit S Low-Power Consumption (80A max) and 16-bit digital-to-analog converters (DACs). The S 14-/16-Bit Resolution in a 3mm x 5mm, 8-Pin MAX5214/MAX5216 are single-channel, low-power, buff- MAX Package ered voltage-output DACs. The devices use a precision S Relative Accuracy external reference applied through the high resistance 0.40 LSB INL (MAX5214, 14-Bit typ, 1 LSB max) input for rail-to-rail operation and low system power 1.2 LSB INL (MAX5216, 16-Bit typ, 4 LSB max) consumption. The MAX5214/MAX5216 accept a wide 2.7V to 5.5V supply voltage range. Power consump- S Guaranteed Monotonic Over All Operating Ranges tion is extremely low to accommodate most low-power S Low Gain and Offset Error and low-voltage applications. These devices feature S Wide 2.7V to 5.5V Supply Range a 3-wire SPI-/QSPIK-/MICROWIREM-/DSP-compatible S Rail-to-Rail Buffered Output Operation serial interface to save board space and to reduce the complexity in isolated applications. The MAX5214/ S Safe Power-On Reset (POR) to Zero DAC Output MAX5216 minimize the digital noise feedthrough from S Fast 50MHz, 3-Wire, SPI/QSPI/MICROWIRE- input to output with SCLK and DIN input buffers pow- Compatible Serial Interface ered down after completion of each serial input frame. S Schmitt-Trigger Inputs for Direct Optocoupler On power-up, the MAX5214/MAX5216 reset the DAC Interface output to zero, providing additional safety for applica- tions that drive valves or other transducers that need S Asynchronous CLR Clears DAC Output to Code 0 to be off on power-up. The DAC output is buffered S High Reference Input Resistance for Power resulting in a low supply current of 80FA (max) and Reduction a low offset error of Q0.25mV. A zero level applied to S Buffered Voltage Output Directly Drives 10kI the CLR pin asynchronously clears the contents of the Loads input and DAC registers and sets the DAC output to zero independent of the serial interface. The MAX5214/ MAX5216 are available in an ultra-small (3mm x 5mm), 8-pin FMAX package and are specified over the -40NC to +105NC extended industrial temperature range.
