What is AD5171?
The AD5171 is a 64-position, one-time programmable (OTP) digital potentiometer2 that uses fuse link technology to achieve the memory retention of the resistance setting function. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors.
What is the principle of AC potentiometer?
The working principle of the AC potentiometer is same as that of the DC potentiometer, i.e., the unknown voltage is determined by comparing it with the known voltage. And when both of them are equal the galvanometer indicates the null point. Hence the value of the unknown emf is known.
What kind of DC supply does an analog potentiometer use?
Analog Devices offers digital potentiometers with dual ±2.5 V, ±5 V, or ±15 V supplies that can handle bipolar or ac operation. The user can still achieve ac operation with a single dc supply by raising the dc offset.
Can a digital potentiometer handle bipolar operation?
A: Yes. Analog Devices offers digital potentiometers with dual ±2.5 V, ±5 V, or ±15 V supplies that can handle bipolar or ac operation. The user can still achieve ac operation with a single dc supply by raising the dc offset.
Where can I find support for digital potentiometers?
A: EngineerZone is an Analog Devices online support community with support for the digital potentiometer available in the Precision DACs community. Customers from all over the world can post questions, view existing questions and answers, and review and contribute to ongoing discussions in this community.
How does a potentiometer work in a circuit?
The potentiometer is just a variable resistor, sometimes also called a rheostat, which you all could have seen in your physics laboratory, it consists of a metal coil wound on a cylindrical platform that consists of a sliding contact that is used to control the resistance of a circuit. A typical Rheostat is shown in the picture below
