Custom designs are easily created using the MAX11300 configuration GUI software. Watch this video to learn (Mandarin) how to create a design using the MAX11300 GUI configuration software and the MAX11300 PMB Evaluation Kit.
PIXI ports provide highly flexible hardware configuration for 12-bit mixed-signal applications. The MAX11300 is best suited for applications that demand a mixture of several analog and digital functions. Each port is individually configurable with up to four selectable voltage ranges within -10V to +10V.
The MAX11300 allows for the averaging of 2, 4, 8, 16, 32, 64, or 128 ADC samples from each ADC-configured port to improve noise performance. A DAC-configured output port can drive up to 25mA. The GPIO ports can be programmed to user-defined logic levels, and a GPI coupled with a GPO forms a logic-level translator.
Internal and external temperature measurements can monitor user-programmable conditions of minimum and maximum temperature limits, using the interupt to notify the host if one or more conditions occur. The temperature measurement results are made available through the serial interface.
The MAX11300 features an internal, low-noise 2.5V voltage reference and provides the option to use external voltage references with separate inputs for the DAC and ADC. The MAX11300 uses a 4-wire, 20MHz, SPI-compatible serial interface for communication with the host. The device operates from a 5V analog supply and a 1.8 V to 5.0V digital supply. The PIXI port driver voltage supply operates from a wide -12.0V to +12.0V.
The MAX11300 is available in a 40-pin TQFN, 6mm x 6mm package or a 48-pin TQFP, 7mm x 7mm package specified over the -40°C to +105°C temperature range.

Description
The MAX11300PMB1 peripheral module (Pmod™) provides the necessary hardware to interface the MAX11300 20-channel programmable mixed-signal I/O device to any system that utilizes Pmod-compatible expansion ports configurable for SPI communication. The device is a 12-bit multichannel analog-to-digital converter (ADC) and a 12-bit buffered DAC output in a single IC. This device also includes software-configurable general-purpose I/O ports. A local and two remote temperature sensors keep track of junction and environmental temperatures. Adjacent pairs of ports can also be used as logic translator or analog switch. Each pin can also be used as a positive input of a comparator with programmable threshold.
