Learn Analog Op-Amps Circuit Design

delabs Op-Amp Circuits (painstakingly) updated, The basic circuits and notes. some related resources in those pages too. An interactive tutor is also available.Learn Analog Op-Amps Circuit Design

Analog Electronics Tutorials


This is just a formatted-edited email thread exported from Eudora from my mailbox using the content concentrator. The circuit above was made by TF a student, This thread for circuit above has been put online to share information. The part under "From: delabs" are my writing. there may be some mistakes and broken links.

Design of a Thermocouple Amplifier.

This is in continuation of the thread called "Design of a Thermocouple Amplifier" doc00023.html which is in the same section .

Design of a ADC Interface for Microcontroller.

I need a few tips from you on Analog design in general: I have seen that a lot of ADCs have a separate AGND and DGND, but they are shorted at the chip. I believe this is required to keep the noisy digital return paths sperate from the analog return paths.

Clean Rooms and Electronics

Clean rooms and Dust free environment is a must for Precision Mechanical Engineering. It is not MEMS or nano sizes, even micron sizes accuracy in parts can be affected by Dust and Humidity.

In Electronics, Timepiece Manufacturing, Medical Equipment and Scientific Apparatus companies. Clan Rooms ensure long term reliability and safety of the products not to forget Precision.

EE Design Library - Electronic Product Design Resource.

Even if a Place is partially Dust free, it is better to have all objects with the least surface area. The way Motors are designed, Interiors of houses even a Machine

Clan Rooms and Electronics

You can enclose objects with many contours and unclean-able surfaces within a Spherical or Cubical Transparent Cover, this is easy for inspection and cleaning.

Dust, Oil, Sand and Humidity makes Grime. Never allow Rodents and Roaches in the Workplace they are larger than 100 microns.

Tools and Equipment must be maintained free of rust/corrosion and exposure to brine or chemical fumes. Metal tools must be cleaned, oiled and stored in dry places when not in use.
