MAX1169 ADC Analog-to-Digital converter

This application note describes how to interface a MAX1169 analog-to-digital converter (ADC) to a PIC microcontroller. It includes an example circuit and software for a PIC18F442. The software contains function calls to interface the ADC to the PIC microcontroller using the internal MSSP I²C port at 400kHz.

What is the use of a Robot, which cannot perceive its environment in detail. Where can a Control system be effective, if it does not get a "feedback" about its actions. How could one do Analysis and Research or Verify, when he cannot Measure a parameter with good accuracy and resolution.

ADC are the Eyes and Ears for a uC, this brings the Real world as Numbers within the CPU. Without ADC a uC is like a Frog in the Well and has to create an Imaginary World for himself. That is beyond the scope of Engineering.

Bring your favorite PIC Microcontroller to his senses. Give him an ability to Perceive the Reality around him. Get him an Analog to Digital Converter and don't forget to code.

An ADC must be better than 4 1/2 Digit Value. For me the Intersil chip 7135 is a Benchmark. Beyond 5 1/2 Resolution may be needed only for Scientific Research.

I would say, 2 1/2 is like Analog Meters/Bar Graphs, 3 1/2 for Control systems, 4 1/2 for T&M and beyond 5 1/2 is for R&D.
