September 2021 Updates

• Added a “How They Work” section to the Analogue Switches page, including a circuit diagram.

• Added a new page with info on the SC-89 component package.

• Added a model of the input offset voltage for op-amps, a schematic for external input offset voltage trimming, and info on input offset voltage drift with both temperature and time to the Op-Amps page.

• Added new page called What Are Transfer Functions, Poles, And Zeroes?.

• Add the tutorial: Creating A Scheduled Lambda Function Using AWS CDK.

• Added info on SMD crystal packages.

• Added info on the turnover temperature and oscillation mode of 32.768kHz crystals and the negative resistance test.

• Added info on RTL and SR latches.

• Added info on summing amplifiers to the Op-Amps page.

• Added info, schematics and simulation results for op-amp based level-shifters.

• Condensed the four battery pages (lead-acid, zinc-air, coin cells, lithium thionyl chloride) into a single Batteries page.

• Condensed the diode pages (TVS diodes, LEDs, Zener Diodes, General Purpose Diodes) into a single page.

• Added info, schematics and equations for op-amp based ideal diodes and half-wave rectifiers.
