概述

Description

AD5293BRUZ-50 is an Analog Devices digital potentiometer (digipot). It provides a programmable resistance between terminals A and B under control of a serial interface (SPI-like). The device offers discrete wiper positions (typically 256 taps for 8-bit resolution) which lets you adjust gain, offset, or attenuation in analog circuits and for calibration tasks. The BRUZ package denotes the 8-lead package style, and the “-50” suffix indicates industrial temperature range (about -50°C to +125°C). Exact end-to-end resistance (Rab) and electrical characteristics depend on the specific variant; consult the datasheet for precise values and operating limits. Common applications include programmable gain stages, sensor conditioning, attenuators, and test/calibration gear.

Features

Key features of AD5293BRUZ-50:
- End-to-end resistance: 50 kΩ (nominal)
- Wiper resolution: 6-bit control (64 positions)
- Interface: I2C-compatible serial interface (2-wire)
- Configurations: Potentiometer or rheostat mode
- Supply voltage: 2.7 V to 5.5 V (single-supply operation)
- Low power: suitable for battery-powered/low-current apps
- Package: 8-pin, BRUZ-50 RoHS package variant
- Temperature range: industrial/mid-range (typical operating range specified in datasheet)
- Nonvolatile/volatile memory: wiper setting stored in register (specs vary by variant; consult datasheet for NV options)
Note: Exact specs (e.g., exact temperature range, memory behavior) should be confirmed in the latest Analog Devices datasheet for the BRUZ-50 variant.

Package

It’s an 8‑lead MSOP (µSOP) package, RoHS compliant (lead‑free).

Pinout

- Pin count: 8 pins (in an 8-pin package such as MSOP/SOIC).
- Function: A 1-channel digital potentiometer with A, B end terminals and a Wiper (W). It is controlled by a serial interface (SPI-like) using CS, SCLK, and SI (data in); powered by VDD and GND.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A US-based multinational semiconductor company that designs, manufactures, and markets analog, mixed-signal, and DSP integrated circuits for industrial, automotive, communications, and consumer applications.

Application

Typical application areas for AD5293BRUZ-50:
- Programmable gain/attenuation in op-amp feedback networks
- Programmable voltage dividers for references and biasing
- Calibration and trimming in instrumentation, ADC/DAC calibration, and sensor interfaces
- Audio volume control and programmable attenuators
- Test/measurement equipment requiring adjustable attenuation
- Feedback networks in control loops (servo/motor applications)
