Comparing the Labrador
Where I compare the Labrador with the $300 Digilent Analog Discovery 2 and determine if using a “rail-to-rail” operational amplifier matters.
Where I explore filters in electronics and use the Espotek Labrador to demonstrate how to understand filters and create amplitude response curves.
Op Amp Resources
Here are links to Operational Amplifier information, primarily for the design of simple, practical amplifiers.
Labrador Lesson: Programmable Bias and Gain
Using potentiometers for programmable bias and gain on the amplifier.
Designing an Inverting Amplifier with Bias
I’ll use this amplifier to perform multiple tests using the Espotek Labrador.
