Testing and Measurement Notes - 01
If the waveform on the scope droops then you may need to use a 10X attenuating probe or mode. this attenuator is at the tip of the probe hence better measurement possible, also very high frequency signals may be best transmitted over a 50 ohm impedance matched line to the Oscilloscope. The History of Oscilloscope, [...]
The Spice in Analog Design
Analog Designers created Spice, Analog Design Professionals are adding their experience in many commercial and free spice EDA tools. When you are creating a new demanding design, a working solution is achieved by combining workbench and simulation work.
Lab Test Bench and Breadboard testing needs to be done along with analog simulation. Power and mixed signal [...]

LM335-336 - LM335 is a temp sensor, LM335 . use it for temp for CJC. Temperature Sensors - RTDs and Thermocouples, - Chapter 6: Temperature Measurement.
LM336-2.5 is an voltage Reference. recision 2.5V shunt regulator diodes, Applied as a precision 2.5V low voltage reference for digital voltmeters, power supplies or in opamp signal conditioning. Current Loop [...]
BD139 and BD140 Complementary transistor
BD139 and BD140 Complementary transistor
This pair is my favorite when driving small solenoids or motors. SOT-32 12 Watts..
BD139 - NPN, 80V and 1.5A, 40 beta min. BD140 - PNP, 80V and 1.5A, 40 beta min.
This means any small solenoid, relay or DC motor can be controlled with this. I would use it upto 24V DC [...]
