AD8403AR50-REEL

Overview

The AD8403AR50-REEL is a quad-channel, 256-position digital potentiometer from Analog Devices. It provides four independent variable resistors with a nominal resistance of 50 kΩ and a linear taper. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and features an SPI-compatible 3-wire serial interface for data input. Each channel includes a volatile latch to maintain the wiper position. The component is housed in a 24-lead surface-mount package and is designed for industrial temperature ranges.

Feature Summary

Quad-channel configuration with four independent 256-position variable resistors
Nominal end-to-end resistance of 50 kΩ with ±1% channel-to-channel matching
SPI-compatible 3-wire serial interface supporting daisy-chaining via SDO pin
Power shutdown mode reduces current consumption to less than 5 μA

Applications

Mechanical potentiometer replacement
Programmable filters, delays, and time constants
Volume control and panning circuits
Line impedance matching
Power supply adjustment

Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing. Confirm the 'AR' designation corresponds to the required operating temperature range and package style. Ensure compatibility with existing PCB footprints for the 24-lead variant specified in the datasheet.

Selection Notes

Select this model for applications requiring four digitally controlled variable resistors with a 50 kΩ value. The 50 kΩ version offers a bandwidth of 125 kHz at -3 dB. Consider the 10 kΩ or 100 kΩ variants if different resistance values or bandwidth characteristics are needed for the specific circuit design.

Part Context

This component belongs to the AD8400/AD8402/AD8403 family of digital potentiometers. The AD8403 specifically denotes the quad-channel version, distinguishing it from the single-channel AD8400 and dual-channel AD8402. All members share similar electrical characteristics and interface protocols.

Replacement Considerations

Direct replacements within the same family include AD8403AR10 (10 kΩ) and AD8403AR100 (100 kΩ). Verify that the substitute part number matches the required resistance value and package type before implementation.
