A resistive divider is a type of passive electrical circuit that divides the input voltage into two outputs proportional to the input voltage. Resistive dividers are used for binary-weighted voltages as well as analog signals.
The resistive divider comprises three diodes, two resistors, and a capacitor. An analog signal will be converted into a digital signal in this circuit after going through this component.
Working principle Of A Resistive divider
Now the real-world question is, how does a resistive divider work? A resistive divider is a circuit that converts the input voltage into two output voltages. The output voltages will be proportional to the input voltage, and the resistor values determine their ratio.
The resistive divider has a voltage divider and an amplifier at its outputs. At its inputs, it has a resistor R1 and R2; at its outputs, there are two resistors, R3 and R4. The resistances of all these resistors should be equal.
Otherwise, the amplifier will amplify both outputs equally, which will result in an output voltage larger than the input, which is not desirable as it can damage or overload components downstream from it.
Resistive Dividers Structure
A resistive divider is a passive network composed of two resistors, R1 and R2. Resistors are selected so that one is twice as large as the other. Typically this means that resistor R1 has a resistance of 2Ω while resistor R2 has a resistance of 4Ω.
There are many applications for the layout of the resistive dividers, including signal generators, frequency dividers, phase shift oscillators, and power voltages which change linearly with time.
Types of Resistive divider
Resistive dividers are also called resistors. They are devices that restrict the flow of electrons in a circuit, thereby reducing the total current.
The resistors are classified into two types based on their construction: wire-wound resistor and thin-film resistor. The wire-wound type is also known as pot than the thin film type.
The wire-wound resistors are built with an insulated wire wound around a ceramic body, while the thin-film resistors use layers of metal oxide to create resistance.
Resistive Divider Uses
Resistive dividers are used in many applications. It is the most common type of divider for PCB layout. A resistor divider is a series of resistors connected in parallel, used to reduce an input voltage to the desired output voltage. Resistive dividers are also used in many applications.
It is the most common type of divider for PCB layout. Resistive dividers produce AC signals by applying AC voltage to the resistive material.
It can be used in various applications that require accurate voltage measurement. They are also known as voltage dividers or potential dividers.
Some uses of resistive dividers include measuring the output voltage of power supplies, detecting the presence and polarity of a signal on a conductor, and measuring the output of digital electronics such as op-amps.
