AD5204BRUZ100-R7

Introduction

The AD5204BRUZ100-R7 is a Digital Potentiometer that integrates a resistor array, analog switch, control logic, and nonvolatile memory into a 16-pin package. It is suitable for both single-ended and differential systems. The device includes 256 wiper positions, with 8-bit resolution, allowing a range of 256 taps between 0 and 100% of the total resistance of 100 kΩ. This device offers low power consumption, high accuracy and reliability, and the ability to easily adjust the wiper position from a microcontroller.

Application Field

The AD5204BRUZ100-R7 is designed for a wide range of applications, including audio and video crossover networks, preamplifiers, balanced line drivers, amplifier power supplies, and low current adjustment control. Additionally, the device can be used for impedance and load matching, as well as for controlling the impedance of dynamic microphones.It is ideal for data acquisition systems, where it can be used to adjust the amount of input signal that is acquired. It can also be used to adjust the gain of analog-to-digital converters, as well as for image processing and image stabilization systems.

Working Principle

The AD5204BRUZ100-R7 is operated by either an 8-bit digital control word or a serial control port. The 8-bit control word sets the wiper position of the digital potentiometer. The serial port is used to communicate with a host microcontroller, allowing for a higher level of control.The internal nonvolatile memory stores the last programmed value for the wiper position. This provides the benefit of returning to a known state when the device is turned off or reset.The resistor array consists of 256 resistors that are activated by the wiper selector according to the 8-bit control word. The total resistance of the array is 100 kΩ. The analog switch activates the corresponding resistor in the array, and the resulting voltage is proportional to the value of the 8-bit control word.

Conclusion

The AD5204BRUZ100-R7 is a digital potentiometer that is suitable for a wide range of applications. It offers low power consumption and high accuracy, with the ability to adjust the wiper position from a microcontroller. It is suitable for data acquisition systems, where it helps adjust the input signals and the gain of analog-to-digital converters. The internal nonvolatile memory provides the benefit of returning to a known state when the device is turned off or reset.
