Original description

The production kit of this logic test pen is mainly used to introduce a logic pen that uses a piece of CD4511BE to control the display of a digital tube. The CD4511BE includes two independent, high gain, internal frequency compensation dual operational amplifiers.  Suitable for single power supply with a wide power supply voltage range, and also suitable for dual power supply working mode. Under the conditions, the power supply current is independent of the power supply voltage.

      Its use range includes sensor amplifiers, DC gain  modules, audio amplifiers, industrial controls, DC gain components and all other applications that can be powered by single power supply.

 

Color ring recognition method:
Black 0, brown 1, red 2, orange 3, yellow 5, green 6, blue 6, purple 7, ash 8, white 9, gold, silver
The five -color ring resistance refers to the resistance of the resistance value with five color rings, and the number of
As shown in the figure.The first color ring represents the largest number of the resistance value; the second color ring
The second digit of the resistance value; the third color ring represents the third digit of the resistance value;
The fourth color ring represents the multiplication of the resistance value; the fifth color ring represents the range of errors.
For example, with a five -color ring resistance, the first ring is red (represents 2), and the second ring is red
(Representative 2), the third ring is black (represents 0), the fourth ring is black (represents doubled),
The fifth ring is brown (represents±1%), then its resistance value is 220Ω×1=220&Osga ;,

 

The scope of error is± 1%.
