The MAX11301 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 high-voltage, 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.

Custom designs are easily created using the MAX11301 configuration GUI software. Watch the video below to learn how to create a design using the MAX11300 GUI configuration software and the MAX11301 Evaluation Kit.

PIXI ports provide highly flexible hardware configuration for 12-bit mixed-signal applications. The MAX11301 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 MAX11301 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 MAX11301 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 MAX11301 uses a 400kHz I²C-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 -12.0V to +12.0V.

The MAX11301 is available in a 40-pin TQFN, 6mm x 6mm package or a 48-pin TQFP, 9mm x 9mm package specified over the -40°C to +105°C temperature range.

Product Detail

Maxim Integrated brings the convenience of remote health monitoring to your fingertips. The modular architecture allows for a variety of systems to be assembled quickly and easily within a couple of minutes. The system flexibility stems from the FeatherWing® form factor that provides a plug-and-play interface by adding or removing desired sensors, enabling or disabling a particular sensor, and the frequency data transmission to an online dashboard. The system is built on a Maxim Integrated low-power microcontroller to ensure minimum power consumption for designs on the go.
