Evaluates: MAX11311 MAX11311PMB Peripheral Module General Description Benefits and Features The MAX11311PMB peripheral module (Pmod) provides Up to 12 12-Bit ADC Programmable Inputs the necessary hardware to interface the MAX11311 Up to 12 12-Bit DACs with 25mA Current Capability 12-channel programmable mixed-signal I/O device to any 70mA max at +12V with On-Board Power Supply system that utilizes Pmod-compatible expansion ports 30mA typ at -12V with On-Board Power Supply configurable for SPI communication. The device is a 12-bit Use External Power Supply at VDDIO (VDDIO multichannel analog-to-digital converter (ADC) and a Jumper Removed) if More Current is Needed 12-bit buffered DAC output in a single IC. This device also Up to 12 Digital I/Os includes software-configurable general-purpose I/O ports. Up to 12 Comparator Inputs A local and two remote temperature sensors keep track of Internal or External Reference for ADC and DAC junction and environmental temperatures. Adjacent pairs of ports can also be used as logic translator or analog Individually Selectable ADC References for Each Port switch. Each pin can also be used as a positive input of a Internal Temperature Sensor comparator with programmable threshold.

Peripheral Module Board Photo Pmod is a trademark of Digilent Inc. 19-7768 Rev 0 2/16Evaluates: MAX11311 MAX11311PMB Peripheral Module Detailed Description SPI Interface X1 The MAX11311PMB Pmod can plug directly into a Pmod-compatible port (configured for SPI) through the INTB 7 1 CS X1 connector. For information on the SPI protocol, refer to the MAX11311 IC data sheet. Connector X1 provides connection of the module to 8 2 MOSI the Pmod host. See Table 1 and Figure 1 for detailed description. 9 3 MISO Connector JP1 provides selection of +3.3V either from the PMOD SUPPLY or an external supply, X2. Connectors SV1 and SV2 provide connection to the CNVTB 10 4 SCLK IC pins (MAX11311 ports 011). Connector SV3 is ground. GND 11 5 GND Connectors EXT TEMP1 and EXT TEMP2 provide connection to the external temperature sensors. 3.3V 3.3V . 12 6 Connector VDDIO provides connection to the AVDDIO pins of the device, which is connected to the +12V power supply SPI Connector VSSIO provides connection to the AVSSIO pins of the device, which is the analog negative supply for mixed-signal ports. Install VSSIO from 1 to 2 to Figure 1. X1: Pmod SPI Connector Pin Configuration connect AVSSIO to ground. Install VSSIO from 2 to 3 to connect AVSSIO to -12V. Table 1.
