概述

Description

The AD5243BRMZ100-RL7 is Analog Devices’ dual digital potentiometer with an I2C-compatible serial interface. It contains two potentiometer elements, each with an end-to-end resistance of 100 kΩ, allowing programmable resistance dividers or attenuators in analog signal paths. Wiper positions are set via I2C commands, enabling software-controlled gain, offset calibration, or programmable voltage references. The BRMZ package is a RoHS-compliant, small-outline package, and RL7 denotes reel packaging. Typical uses include audio/gain control, sensor calibration, programmable attenuators, and DC level setting in analog circuits. For exact specifications—residual voltage ranges, I2C addresses, resolution, power requirements, and memory behavior—consult the AD5243 datasheet.

Features

Here are the typical features of the AD5243BRMZ100-RL7 (digital potentiometer family):
- I2C-controlled digital potentiometer (rheostat/potentiometer configuration)
- End-to-end resistance: 100 kΩ (nominal)
- 256 wiper steps (8-bit resolution)
- Nonvolatile memory option to store last wiper setting
- Wide supply range: roughly 2.7 V to 5.5 V
- I2C interface, compatible with standard/fast-mode (up to 400 kHz)
- Low quiescent current; power-down/idle modes
- 8-pin package (MZ/RL7 family): compact, RoHS-compliant
- Operating temperature typically -40°C to +125°C (industrial)
- Suitable for precision gain/voltage divider adjustments, attenuators, and programmable analog circuits
Note: exact parameters (voltage range, address bits, NV options) are in the datasheet; confirm for your specific lot.

Package

8-pin MSOP (MSOP-8) package.

Pinout

- Pin count: 8 pins (MSOP-8 package, AD5243BRMZ100-RL7)
- Function: One-channel digital potentiometer with I2C interface; end-to-end resistance 100 kΩ; terminals A and B form the resistive element, W is the wiper; supplies VDD and GND; uses SDA and SCL for I2C communication.
