概述

Description

AD5258BRMZ1 is Analog Devices’ eight-channel digital potentiometer (DPOT). It provides eight independently adjustable wipers controlled over a serial interface (I2C-compatible). Each pot lets you program its end-to-end resistance and wiper position to implement programmable attenuation, gain, offset trimming, or signal conditioning in analog paths. The device supports volatile wiper settings with optional nonvolatile memory to retain values after power-up, along with typical DPOT features such as low power operation and flexible addressing. The BRMZ1 suffix indicates a RoHS-compliant package; exact package type, pinout, and electrical specs are defined in the AD5258BRMZ1 datasheet. For precise values (end-to-end resistance, resolution, timing, and demo/app notes), consult the official datasheet or product page.

Features

Key features of AD5258BRMZ1 (Analog Devices):
- I2C serial interface for easy microcontroller control
- Eight potentiometer elements in a single package (multi-channel digital pot)
- End-to-end resistance options (e.g., 5 kΩ, 10 kΩ, 50 kΩ variants)
- 256-step wiper resolution per channel (8-bit control)
- Nonvolatile and volatile memory to preserve wiper settings
- Low-power operation with standby modes
- Wide supply voltage range (typical 2.7–5.5 V)
- Temperature range suitable for industrial use (-40°C to +125°C)
- RoHS-compliant packaging (BRMZ1)

Package

8-pin MSOP package (MSOP-8), RoHS-compliant.

Pinout

- Pin count: 8 pins (MSOP-style package, BRMZ1)
- Function: One-channel digital potentiometer with I2C-compatible interface. Provides a programmable resistance between terminals A and B with wiper at W; uses VDD and GND plus SDA and SCL for programming.

Manufacturer

Analog Devices, Inc. (ADI). It is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP (digital signal processing) integrated circuits, including digital potentiometers like the AD5258.

Application

- Programmable gain, attenuation, and offset trimming in op-amps, ADCs, DACs
- Audio/line-level volume control and path attenuation
- Sensor/bridge calibration and front-end gain matching in instrumentation
- Test and measurement equipment for automated calibration
- RF/IF front-end attenuation and programmable impedance/matching networks
- Automotive/industrial signal conditioning with software-controlled resistance
