Working Principle

The AD5162BRM10 Digital Potentiometer is an integrated circuit consisting of a resistor array, associated logic, an SPI interface, and digital control logic. The resistor array is divided into multiple taps, which can be individually adjusted with digital control signals. The digital control signals are provided by an SPI interface. During operation, the digital control signals are used to control the resistance between any two of the 256 taps.TheAD5162BRM10 Digital Potentiometer enables the user to digitally program and adjust the resistance between any two of the taps in the resistor array. With 256 available taps, the circuit can be adjusted from 1Ω to 10KΩ in 1Ω increments. The user can select any two of the taps to set the resistance between them. This provides a high degree of programmability and flexibility to the user.The AD5162BRM10 Digital Potentiometer also consists of an internal non-volatile memory, which stores the resistance values of the taps and allows the user to store and recall different resistance values. The internal non-volatile memory allows the user to store the setting of the device even while the power is off.

Conclusion

The AD5162BRM10 Digital Potentiometer is a digitally controlled, 256-tap device which is used to replace traditional mechanical potentiometers or traditional digital pots. The AD5162BRM10 Digital Potentiometer is used in a wide range of applications, from volume control in consumer electronics to transformers, pumps and motors in industrial automation to antennacontrols for wireless communications. The device is also used in feedback loops for precision control of motors and transformers, as well as for voltage divider circuits. The AD5162BRM10 Digital Potentiometer contains a resistor array with 256 taps and a corresponding SPI interface for digital control. The internal non-volatile memory enables the user to store and recall different resistance values. This makes the AD5162BRM10 Digital Potentiometer an ideal candidate for a wide range of data acquisition, digital potentiometer and interface applications.
