概述

Description

AD526JN is a digitally controlled potentiometer (DCP) from Analog Devices. It behaves like a three-terminal potentiometer (A, B, and W) with a fixed end-to-end resistance (RAB) that you set via a serial control interface. The wiper position is programmable, allowing precise gain/attenuation in feedback networks, analog front ends, logarithmic/linear applications, and sensor conditioning.
Key points:
- Serial interface: SPI- or I2C-compatible control (depends on the specific variant).
- End-to-end resistance: typically around 100 kΩ (values vary by part).
- Wiper resolution: many variants offer 256 steps (8-bit), enabling fine adjustments.
- Packaging: JN suffix denotes a plastic DIP package.
- Variants may be volatile or non-volatile (check datasheet for memory type and exact specs).
Use it where you need programmable, stable resistance in an analog signal path. For exact specs and interface details, consult the specific AD526JN datasheet.

Features

AD526JN is an Analog Devices digital potentiometer (DigiPot). Key features:
- 8-bit wiper resolution (256 steps) across the end-to-end resistance (RAB)
- SPI-compatible serial interface for programming the wiper
- End-to-end resistance options available (e.g., 5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ; select per variant)
- 8-pin DIP package (suffix N indicates DIP)
- Low-power operation suitable for battery-powered and portable apps
- Ideal for programmable gain/attenuation, offset trimming, and adjustable voltage dividers
Note: Check the exact RAB value, supply range, and temperature range in the specific AD526JN datasheet for your part revision.

Package

AD526JN comes in an 8-pin plastic DIP (DIP-8) through-hole package.

Pinout

8 pins. It is a digitally controlled potentiometer (digital pot) with A, B, and W (wiper) terminals; the resistance between A and B is set by a digital control input via a serial interface.

Manufacturer

Analog Devices, Inc. (ADI) manufactures the AD526JN. Analog Devices is a US-based multinational semiconductor company that specializes in high-performance analog, mixed-signal, and digital signal processing (DSP) integrated circuits, including amplifiers, data converters, sensors, and related components.

Application

AD526JN is a digital potentiometer. Typical applications include:
- Programmable gain/attenuation in op-amp circuits
- Audio volume and tone control
- Sensor and ADC/DAC calibration and trimming
- Programmable attenuators in signal conditioning
- Adjustable feedback networks in instrumentation and control systems
- Automatic level control (AGC)
- Test equipment calibration networks
- Servo/actuator control requiring a variable resistor divider

Equivalent

AD526JN is an 8-bit SPI digital potentiometer with 100 kΩ end-to-end resistance in an 8-pin package. Common equivalents from other vendors include:
- Microchip MCP41/MCP42 series (100 kΩ SPI digipots)
- Analog Devices AD5200/AD5204 family (SPI digipots)
- TI DS180x family (100 kΩ digipots, I2C)
Notes: exact resistance value, interface (SPI vs I2C), and packaging vary—confirm end-to-end resistance and pinout before cross-referencing.
