Description

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.
