Figure 1. Voltage Divider Circuit. The term “voltage divider” relates to how the circuit works. It comprises two series resistors (R1 and R2) and an input voltage source (Vin) as shown in Figure 1. As determined by Ohm’s Law, the output voltage is ‘divided’ down by the ratio of...
The circuit based on a photoresistor uses a resistor divider to allow the high impedence Analog input to measure the voltage. These inputs do not draw almost any current, therefore by Ohm's law the voltage measured on the other end of a resistor connected to 5V is always 5V, regardless ...
A problem seen at high frequencies is that stray (parasitic) capacitance effects with the overall response of a resistive voltage divider. The simplest way to correct for this problem is to introduce capacitors in parallel to the resistors. Consider the divider circuit in Figure 3. Capacitor C2,...
This circuit has the disadvantage of requiring extra components and that the R3/R4 divider creates a small, but continuous, load on the battery. Most of these components are tiny. MP1 and Q1 are not power devices and can usually be found in small packages like a SOT23-3, an SC70-3 or...

In the circuit a voltage divider is set up between R1and the resistance of D1. The current in D1is varied by changing the current in R2. When the current in D1is small rDis large and the fraction of the input signal seen at the output is large. As the current in D1increases, it...
1. Voltage divider for setting VMID: Using section 2 of Design Considerations, for the circuit in Figure 1, the values for the peripheral components are set to R1 = R2 = 1 MΩ to keep the supply current contribution around 1 µA. ...
In addition, the reference voltage is often a non-standard value (like 100mV or 409.6mV) so a reference voltage divider circuit is often used. Versus Sigma-Delta ADC The sigma-delta ADC uses oversampling to obtain very high resolution. It also allows input bandwidths in the low MHz range...
