19-6321 Rev 0 5/12 MAX5216PMB1 Peripheral Module General Description Features The MAX5216PMB1 peripheral module provides the nec- S High-Accuracy 16-Bit DAC with On-Board essary hardware to interface the MAX5216 16-bit DAC to Precision Voltage Reference any system that utilizes PmodK-compatible expansion S Low Gain and Offset Errors ports configurable for SPI communication. The IC is a S Buffered Voltage Output Directly Drives 10kI single-channel, low-power, buffered voltage-output DAC. Loads The reference voltage for the DAC is provided by a 2.5V output version of the MAX6029 voltage reference (0.15% S Optional External Voltage Reference (Jumper Selectable) initial accuracy, 30ppm/C). Digital noise is minimized by having SPI input buffers powered down after completion S 6-Pin Pmod-Compatible Connector (SPI) of each serial input frame. S Example Software Written in C for Portability Refer to the MAX5216 IC data sheet for detailed informa- S RoHS Compliant tion regarding operation of the IC.
