Overview
The MAX11300 is a highly versatile, 20-channel programmable mixed-signal I/O device produced by Analog Devices Inc./Maxim Integrated. This integrated circuit (IC) combines a 12-bit, multichannel analog-to-digital converter (ADC) and a 12-bit, multichannel, buffered digital-to-analog converter (DAC) in a single package. The device is designed to offer a wide range of configurable ports, making it ideal for applications that require multiple analog and digital functions.
