概述

Description

The AD5254BRUZ10-RL7 is Analog Devices’ four-channel, I2C-controlled digital potentiometer. It provides four independent potentiometer elements, each with a defined end-to-end resistance and a programmable wiper, enabling precise gain/attenuation and calibration in analog signal paths. Each channel supports a resolution of 256 discrete wiper positions (8-bit), and the device can store wiper settings in volatile registers or in nonvolatile memory to retain values across power cycles. It operates from a typical 2.7–5.5 V supply and is packaged in a compact, RoHS-compliant package; the RL7 suffix indicates reel packaging for automated assembly. The AD5254 is suitable for applications such as DAC/ADC calibration, programmable attenuators, sensor front-ends, and audio/automation circuits. For exact electrical specifications (end-to-end resistance options, accuracy, power, and interface details), refer to the AD5254 datasheet.

Features

Here are the key features of AD5254BRUZ10-RL7:
- Quad, I2C-controlled digital potentiometer (four 8-bit wipers)
- End-to-end resistance: 10 kΩ per potentiometer (variant indicated by “-10”)
- 256-step resolution per channel; independent wiper positions
- Can be used as four variable resistors or four voltage dividers
- I2C serial interface with configurable address; supports standard/fast modes
- Supply voltage range typically 1.8 V to 5.5 V
- Wide operating temperature: -40°C to +125°C
- RoHS-compliant; available in tape-and-reel packaging (RL7)
Note: For precise electrical details (tolerances, dynamic resistance, power consumption, exact pinout), consult the datasheet.

Package

8-pin MSOP (MSOP-8) package, RoHS-compliant, shipped on a 7-inch reel (RL7).
