EVALUATION KIT AVAILABLE MAX11300 PIXI, 20-Port Programmable Mixed-Signal I/O with 12-Bit ADC, 12-Bit DAC, Analog Switches, and GPIO General Description The MAX11300 integrates a PIXI™, 12-bit, multichannel, analog-to-digital converter (ADC) and a 12-bit, multichannel, buffered digital-to-analog converter (DAC) in a single integrated circuit. This device offers 20 mixed-signal highvoltage, bipolar ports, which are configurable as an ADC analog input, a DAC analog output, a general-purpose input (GPI), a general-purpose output (GPO), or an analog switch terminal. One internal and two external temperature sensors track junction and environmental temperature. Adjacent pairs of ports are configurable as a logic-level translator for open-drain devices or an analog switch. 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 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 monitor programmable conditions of minimum and maximum temperature limits, using the interrupt 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 device uses a 4-wire, 20MHz, SPI-compatible serial interface, operating from a 5V analog supply and a 1.8V to 5.0V digital supply. The PIXI port supply voltages operate from a wide range of -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.
