Data Acquisition - Digital Potentiometers is a type of device, capable of electronically adjusting the resistance value of an electric circuit, commonly known as a potentiometer. The AD5243BRM100-RL7 is a high-precision, low-power, dual-channel digital potentiometer from Analog Devices. It provides complete resistance ratio (resistor wiper position) control accuracy over the life of the device.

This device is primarily used in systems that require on-the-fly changes in resistance. It is ideal for signal conditioning applications, such as gain and offset trimming, signal routing, signal level adjustments, and analog-to-digital converter calibration. The device provides a low-cost solution with extremely small form factor, allowing it to be used in dense, high-reliability applications.

The AD5243BRM100-RL7 combines a nonvolatile memory element, a digital potentiometer, and a low-power self-timed change logic circuit into a small footprint package. The digital potentiometer includes two independently programmable digital wiper registers and a 22-bit nonvolatile memory register which can be programmed by a simple 2-wire serial interface (SCL and SDA).

The device supports three operation modes: write and register mode, write and move mode, and write and read mode. In write and register mode, the AD5243BRM100-RL7 can write a given resistance ratio value directly to the nonvolatile memory register. In write and move mode, the combination of change logic circuitry and buffer amplifier provides an instantaneous wiper position change. In write and read mode, the AD5243BRM100-RL7 can read the actual wiper position.

The AD5243BRM100-RL7 is specified over the extended temperature range of -40°C to +125°C, and is available in a 7-pin SOT-23 package. It can regulate both AC and DC signals, and comes with an ElectroStatic Discharge protection feature. With its small physical footprint and high performance, the AD5243BRM100-RL7 is an ideal solution for a variety of industrial applications.
