Week #13: (11/28-12/2) SNR, Comparators, Temp Sensor

Post by rjagodowski »

This week we'll finish up our discussion of CMRR and SNR.

We will also discuss an Instrumentation Amplifier on a chip, the Analog Devices AD524. Sample Programmable Gain circuits are shown on Page 16.

Then we begin the discussion on Precision Comparators:

Before we discuss the Precision Comparators, we need to spend a few minutes introducing [url= http://www.evilmadscientist.com/2012/basics-open-collector-outputs/]Open Collector Outputs[/url], in this case, from EvilMadScientist.com

Comparators: LM-339 Data Sheet

This is the website that inspired this week's lab: ermicroblog. There are some typos on the schematics and their description of the circuit operation is misleading, which will be pointed out in class and when we build these circuits in lab. Actually, aside from the circuits, this site isn't so great. LOL

A comparator summary from bristolwatch.com.

Don't print this lab, as an updated one will be given to you, but if you wish to get an early look at it, here's a link to the Comparator/Temp. Sensor Lab .
