Summary of MAX11311 – The Powerful Configurable Mixed Signal I/O
The MAX11311 is the industry's first configurable high-voltage mixed-signal I/O device, integrating a 12-bit ADC, 12-bit DAC, and GPIO capabilities. It features 12 bipolar ports that can be individually configured for various functions, including analog switching and logic-level translation. The chip includes internal and external temperature sensors to prevent thermal runaway and offers flexible voltage ranges with programmable sample averaging. A dedicated GUI tool simplifies register configuration, making it an ideal solution for universal signal processing boards where microcontroller I/O selection is challenging or costly.
Parts used in the MAX11311 Project:
- MAX11311 Integrated Circuit
- PIXI (Programmable Interface eXchange)
- 12-Bit Analog-to-Digital Converter (ADC)
- 12-Bit Digital-to-Analog Converter (DAC)
- Internal Temperature Sensor
- Two External Temperature Sensors
- GUI Programming Tool
- Analog Switch Terminals
- Logic-Level Translator
The MAX11311 is industry’s first configurable high-voltage mixed-signal I/O that allows user-defined ADC, DAC, or GPIO functionality.
Programming MAX11311 is very easy. A nice GUI tool helps to generate the right register values. If you want to make a universal signal processing board with a good number of I/O, it often gets very difficult to select a correct microcontroller. Finally, when you select one, it either has less I/O than you need or has fair enough number of I/O but burns your pocket. But if you know about MAX11311, then you’ve got a perfect solution.
Description:
The MAX11311 integrates a PIXI™, a 12-bit analog-to-digital converter (ADC), and a 12-bit digital-to-analog converter (DAC) in a single integrated circuit. This device offers 12 high voltage, bipolar ports. Each of the ports is configurable as an ADC analog input, a DAC analog output, a general-purpose input output (GPIO), or an analog switch terminal. One internal and two external temperature sensors track junction and environmental temperature. This feature prevents thermal runaway. Adjacent pairs of ports are configurable as a logic-level translator for open-drain devices or an analog switch.
Features:
- Up to 12 12-Bit ADC Inputs
- Single-Ended, Differential, or Pseudo-Differential Range Options: 0 to 2.5V, ±5V, 0 to +10V, -10V to 0V
