MAXIM MAX5217EVKIT#

The MAX5215/MAX5217 are pin-compatible 14-bit and 16-bit digital-to-analog converters (DACs). The MAX5215/MAX5217 are single-channel, low-powered, buffered voltage-output DACs. The devices use a preci­ sion external reference applied through the high resis­ tance input for rail-to-rail operation and low system power consumption. The MAX5215/MAX5217 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. The MAX5215/MAX5217 have an I2C-compatible, 2-wire serial interface that operates at clock rates up to 400kHz. On power-up, the MAX5215/MAX5217 reset the DAC out­ put 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. An asynchronous active-low input, AUX, is provided. This input can be programmed to support clear or load DAC operations, independent of the serial interface. The MAX5215/MAX5217 are available in an ultra-small (3mm x 5mm), 8-pin μMAX package and are specified over the -40℃ to +105℃ extended industrial temperature range.
