Overview

The MAX11301GTL+ 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 MAX11301GTL+ configuration GUI software. Watch this video to learn (Mandarin) how to create a design using the MAX11300 GUI configuration software and the MAX11301GTL+ Evaluation Kit. PIXI ports provide highly flexible hardware configuration for 12-bit mixed-signal applications. The MAX11301GTL+ 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 MAX11301GTL+ 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 MAX11301GTL+ 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 MAX11301GTL+ 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 MAX11301GTL+ 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.
