AD5204BR100

Overview

The AD5204BR100 is a four-channel, 256-position digitally controlled variable resistor from Analog Devices. It features a nominal terminal resistance of 100 kΩ with a temperature coefficient of 700 ppm/°C. The device operates on a single supply of +2.7 V to +5.5 V or dual supplies of ±2.3 V to ±2.7 V. It utilizes a 3-wire SPI-compatible serial interface for programming. Each channel includes an independent latch holding the resistance value. The part supports daisy-chaining via an SDO pin and offers power-on midscale preset functionality.

Feature Summary

Four independently programmable channels with 256 tap positions
Nominal end-to-end resistance of 100 kΩ
3-wire SPI-compatible serial interface with daisy-chain capability
Power-on midscale preset and hardware reset (PR) pin

Applications

Mechanical potentiometer replacement
Instrumentation gain and offset adjustment
Programmable voltage-to-current conversion
Programmable filters, delays, and time constants
Line impedance matching

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and tolerance. The BR suffix typically denotes industrial temperature range and SOIC packaging, but official documentation should be consulted for exact availability and revision status.

Selection Notes

Select this component when a 100 kΩ digital potentiometer is required. Ensure the system voltage falls within the 2.7 V to 5.5 V single-supply or ±2.3 V to ±2.7 V dual-supply range. Consider the 700 ppm/°C temperature coefficient if precision over wide temperature variations is critical.

Part Context

The AD5204BR100 belongs to the AD5204/AD5206 family of digital potentiometers. The AD5204 variant provides four channels, while the AD5206 provides six. These devices are designed to replace mechanical potentiometers in applications requiring remote or automated resistance adjustment.
