Product Details

The MAX5214/MAX5216 are pin-compatible, 14-bit and 16-bit digital-to-analog converters (DACs). The MAX5214/MAX5216 are single-channel, low-power, buffered voltage-output DACs. The devices use a precision external reference applied through the high resistance input for rail-to-rail operation and low system power consumption. The MAX5214/MAX5216 accept a wide 2.7V to 5.5V supply voltage range. Power consumption is extremely low to accommodate most low-power and low-voltage applications. These devices feature a 3-wire SPI-/QSPI^™-/MICROWIRE-/DSP-compatible serial interface to save board space and to reduce the complexity in isolated applications. The MAX5214/MAX5216 minimize the digital noise feedthrough from input to output with SCLK and DIN input buffers powered down after completion of each serial input frame. On power-up, the MAX5214/MAX5216 reset the DAC output to zero, providing additional safety for applications that drive valves or other transducers that need to be off on power-up. The DAC output is buffered resulting in a low supply current of 80µA (max) and a low offset error of ±0.25mV. A zero level applied to the active-low CLR pin asynchronously clears the contents of the 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 µMAX^® package and are specified over the -40°C to +105°C extended industrial temperature range.

MAX5216PMB1

View Detailed Evaluation Kit Information

The MAX5216PMB1 peripheral module provides the necessary hardware to interface the MAX5216 16-bit DAC to any system that utilizes Pmod™-compatible expansion ports configurable for SPI communication. The IC is a single-channel, low-power, buffered voltage-output DAC. The reference voltage for the DAC is provided by a 2.5V output version of the MAX6029 voltage reference (0.15% initial accuracy, 30ppm/°C). Digital noise is minimized by having SPI input buffers powered down after completion of each serial input frame.

Refer to the MAX5216 IC data sheet for detailed information regarding operation of the IC.
