概述

Description

AD5220BRMZ-100 is an Analog Devices digital potentiometer with a 100 kΩ end-to-end resistance between terminals A and B. It offers a programmable wiper (W) position, allowing software-controlled adjustment of resistance in analog circuits. Communication is via a serial interface (SPI-compatible), controlled by a microcontroller to set the wiper position. The device is packaged in an 8-pin RoHS-compliant BRMZ package. Typical uses include gain/offset trimming, programmable attenuators, and sensor calibration in embedded systems. Always consult the datasheet for exact electrical specs, timing, and packaging details.

Features

Here are concise features of the AD5220BRMZ100 (digital potentiometer):
- Dual digital potentiometers with I2C interface
- End-to-end resistance: 100 kΩ (typical)
- 256 wiper positions (8-bit resolution)
- Nonvolatile memory to retain wiper settings (NV capable)
- Supply voltage: 2.7 V to 5.5 V
- Low quiescent current; suitable for battery-powered apps
- Temperature range: -40°C to +125°C
- Package: BRMZ (likely MSOP-8)
- Guaranteed monotonic wiper operation
- Optional shutdown/power-down modes for low power
Note: exact NV behavior and interface details should be confirmed in the latest datasheet.

Package

MSOP-8. AD5220BRMZ100 comes in an 8‑lead MSOP (Molded Small Outline) package, RoHS‑compliant (MZ suffix).

Pinout

- Pin count: 8 pins (MSOP-8/SOIC-8 package).
- Function: Single-channel digital potentiometer with 100 kΩ end-to-end resistance; wiper controlled via an SPI-compatible interface (CS, SCK, SDI) with A, B, and W terminals plus VDD and GND.

Manufacturer

Analog Devices, Inc. (ADI). It is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits, as well as related sensors.

Application

AD5220BRMZ100 is a dual digitally controlled potentiometer (DCP). Common applications:
- Programmable gain/attenuation in op-amp feedback and signal conditioning
- Sensor and ADC/DAC offset/trim calibration
- Programmable voltage dividers and reference generation
- Audio volume control, tone shaping, and impedance matching
- Attenuation and calibration in communication links and instrumentation
- Servo/control-loop tuning requiring remote resistance adjustment
Word count well under 100.

Equivalent

Possible cross-references for AD5220BRMZ100 (digital potentiometer) include:
- Microchip MCP41/MCP42 series (SPI, various end-to-end values like 5k/10k/50k/100k)
- Maxim MAX5251/MAX5252 series (SPI, 128-step pots, various end-to-end values)
- Analog Devices AD5252/AD5254 (I2C, multi-channel variants)
Note: exact substitution depends on interface (SPI vs I2C), number of pots, and end-to-end resistance. Check datasheets and cross-reference tools for precise compatibility.
