AD5204BRUZ100

Overview

The AD5204BRUZ100 is a quad-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 is housed in a 24-lead TSSOP package and supports operation within an extended industrial temperature range of −40°C to +85°C.

Feature Summary

• Quad-channel architecture with 256 programmable positions per channel
• 100 kΩ nominal end-to-end resistance with linear taper
• 3-wire SPI-compatible serial interface with daisy-chain capability via SDO pin
• Power-on midscale preset and hardware reset (PR) pin functionality

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion
• Line impedance matching

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and resistance value. Ensure compatibility with the required serial interface timing parameters. Check for any recent product change notices regarding thermal resistance or ESD ratings. Confirm that the application environment stays within the specified absolute maximum ratings for voltage and current.

Selection Notes

Select this component when a quad-channel digital solution is required with 100 kΩ resistance. Consider the 700 ppm/°C temperature coefficient for precision applications. Verify that the system can accommodate the 12 μA typical supply current. Ensure the PCB layout accounts for the 24-lead TSSOP footprint and thermal dissipation requirements defined in the datasheet.

Part Context

This part belongs to the AD5204 family of 4-channel digital potentiometers. It shares functional similarities with the AD5206 (6-channel) but differs in pin count and channel density. The BRUZ100 designation indicates the commercial/industrial temperature grade, 100 kΩ resistance, and TSSOP packaging. It serves as a direct electronic replacement for mechanical potentiometers in multi-channel systems.
