概述
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.
