Visão Geral

Description

AD526JN is a digital potentiometer (digipot) from Analog Devices. It provides a programmable resistance between terminals A and B with a wiper W; the wiper position is updated via a serial digital interface (SPI-like). This lets you adjust gain, attenuation, or calibration in analog circuits under software control. The JN suffix denotes the package type/grade. The AD526 family comes in various end-to-end resistances (e.g., 10 kΩ, 50 kΩ, 100 kΩ) with a fixed number of wiper steps (typically 128 or 256). Some variants offer nonvolatile memory so settings persist after power-down. They are low-power and easy to interface to microcontrollers, suitable for sensor calibration, audio, and instrumentation. For exact RAB, interface details, and electrical specs, consult the AD526JN datasheet.

Features

AD526JN is an Analog Devices digital potentiometer (DCP) in an 8-pin DIP (plastic) package. Key features:
- 8-bit wiper resolution (256 steps) across end-to-end resistance (variant values include common 10k, 50k, 100k options; AD526JN specifies one of these)
- SPI-compatible 3-wire serial interface for setting the wiper (CS, CLK, SI/SDO)
- Single-supply operation from about 2.7 V to 5.5 V
- Low power consumption
- Industrial temperature range (typ. -40°C to +85°C)
- Applications: programmable gain/attenuation, precision voltage dividers, calibration, and servo/automatic gain control
Note: exact end-to-end resistance and any nonvolatile memory options are variant-dependent—check the datasheet for the specific AD526JN part you have.

Pinout

AD526JN is an 8-pin DIP digital potentiometer (the “N” denotes DIP). It provides A, B, and W (wiper) ends of a potentiometer plus VDD and VSS supply pins, and three control pins (CS, SCK, SI) for a 3‑wire SPI‑like interface to set the wiper position. No readback is provided.

Manufacturer

- Manufacturer: Analog Devices, Inc. (Analog Devices).
- Company type: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and digital-signal-processing integrated circuits for a wide range of industries.

Application

AD526JN is a digitally controlled potentiometer. Common application areas include:
- Audio: volume, gain control, tone/balance adjustment
- Signal conditioning: programmable gain/attenuation in op-amps and filters
- Instrumentation: offset and gain calibration, reference trimming
- Test/measurement: adjustable attenuation and signal routing
- Control loops: feedback networks in amplifiers and servos
- RF/telecom: programmable attenuators and gain control in front-ends
- User interfaces: digitally adjustable controls in instruments and portable devices
These use cases leverage its digitally programmable resistance to replace mechanical pots for precision, repeatability, and remote control.

Package

8-pin plastic DIP (DIP-8) package.
