FREE Analog Engineer’s Circuit Cookbooks from Texas Instruments

Today over on the EEVblog forum I learned about the two ebooks available from Texas Instruments. One is for amplifier circuits and the other for data-conversion circuits, including both Analog-to-digital converter (ADC) circuits and Digital-to-analog converter (DAC) circuits. I had to sign up for an account before I could download…

Texas Instruments Datasheets

I was watching The Differential Pair Becomes an Op-Amp – Transistors 101, episode 18 and they mentioned this datasheet: https://ti.com/lit/ds/symlink/lm358.pdf. That URL looks very hacker friendly to me, if you know what you’re looking for you can probably guess the URL! I haven’t tried this in anger yet, this is just a note for Future John.

Graphing calculator

I’m keeping my eye out for a graphing calculator. Haven’t got the money to buy one just yet, but am watching eBay to get an idea of the prices. You can see at Officeworks the choices are basically:

  • HP Prime Graphing Calculator
  • Casio Classpad Colour CAS Calculator fx-CP400
  • Casio Colour Graphic Calculator fx-CG50 AU
  • Texas Instruments Inspire Calculator CXII-CAS
  • Texas Instruments Graphing Calculator TI-84 Plus CE
