MAX11312

MAX11312 EVALUATION KIT AVAILABLE PIXI, 12-Port Programmable Mixed-Signal I/O with 12-Bit ADC, 12-Bit DAC, Analog Switches, and GPIO General Description The MAX11312 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 12 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 MAX11312 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 the -10V to +10V range. The device 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 maxi...
