Electronic Potentiometer Circuit Circuit Diagram A digital potentiometer serves the same function as a potentiometer in hardware in that it varies resistance output. The difference is a digital potentiometer IC is controlled by software, while a regular potentiometer is controlled manually by a person. Just like a regular potentiometer, a digital Pot IC comes in all different values of
This design of digital POT is considered as an illustration of linear taper. The total number of steps in this resistive ladder defines the resolution of the device. The below picture shows the digital potentiometer circuit diagram in ladder design. The digital resistors are regulated through up/down signals or by protocols like SPI and I 2 C.

It also makes the circuit diagram a little bit nicer-looking I think. Wiring Example #3: Potentiometer as Volume Control. This example uses all three pins of the potentiometer to create a simple way of adjusting the volume of an audio amplifier.
In this second design we investigate the IC X9315 which is actually a solid state digital potentiometer and could be used exactly like a mechanical potentiometer, but through logical supply inputs. The IC X9315 from Intersil, is a digitally controlled solid state potentiometer, which internally possesses an array of resistors, wiper switches, a the digital potentiometer. RAB is the nominal resistance across the entire potentiometer, from pin A to pin B. RBW is the resistance between pin B and pin W of the digital potentiometer. n is the number of digital potentiometer bits. For the MCP4XXXX family of potentiometers, the number of bits is eight. Dn is the digital code in decimal form The digital potentiometer (digipot) is a processor-controlled, โข The required resistance value, often called end-to-end resistance, is determined by the design considerations of the circuit. Vendors offer resistances between 5 kilohms (kฮฉ) and 100 kฮฉ in a 1/2/5 sequence with some other intermediate values.
2 Digital Potentiometer Circuits Explained Circuit Diagram
A digital potentiometer is an essential component in the circuit of any electronic device. It's a variable resistor that can be used to control the voltage and current of a circuit. In this article, we'll discuss the importance of digital potentiometers and how they're used in circuit diagrams.
