AD5274BRMZ-20 Data Acquisition - Digital Potentiometers

The AD5274BRMZ-20 is a digital potentiometer from Analog Devices. It is a versatile device that can be used in a variety of applications, from medical equipment to avionics systems. Additionally, it can be used to enhance the sound clarity in audio systems.This device is capable of providing a wide range of resistive values, ranging from 5Ω to 10KΩ, in 256 single-step increments. This great resolution makes this device very suited for signal conditioning applications. Moreover, the AD5274BRMZ-20 features excellent temperature stability over the full -40°C to +125°C temperature range. To take advantage of the full potential of this digital potentiometer, it is usually used as part of multi-stage gain applications. This device is implemented before the signal is amplified by a discrete amplifier, in order to finely control the amplitude of the signal. This is important for controlling the full scale range of transducer outputs. The AD5274BRMZ-20 is also very suited for applications that require low power consumption. The device offers an ultralow shutdown current of only 0.2 μA, and a power consumption of less than 10 μA during operation. Additionally, it is specified for a wide 2.7 V to 5.5 V supply voltage operation, reducing the risk of voltage levels mismatch.The AD5274BRMZ-20 device is extremely easy to use and allows fast, easy implementation in a wide range of different applications. The device can be controlled through two independent control lines, allowing two-wire, three-wire, or four-wire digital control. The device features also a wide temperature range, making it suitable for portable applications. In addition to its application in signal conditioning, the AD5274BRMZ-20 can be used for precision control and calibration of output voltages. Variations in output voltage level can be precisely controlled with only two wires. The AD5274BRMZ-20 is also commonly used in automated test systems, providing precision control of analog output or providing feedback from a control system. In terms of its physical characteristics, the AD5274BRMZ-20 comes in a package with a 3 mm x 3 mm x 0.8 mm SOIC-8 footprint. This package is also RoHS compliant, making it usable in systems where RoHS compliance is required. In conclusion, the AD5274BRMZ-20 is an excellent choice for digital potentiometer applications that require a wide range of single-step resolution, combined with low power consumption. Its fast and easy configuration makes this device especially suited for precision control, calibration, signal conditioning and automated test systems.
