AD5204BRUZ10-REEL7

Overview

The AD5204BRUZ10-REEL7 is a quad-channel digital potentiometer IC from Analog Devices, featuring 256 programmable positions per channel. It utilizes a 3-wire SPI-compatible serial interface for data input and includes a serial data output (SDO) pin to support daisy-chaining configurations. The device operates on a single supply voltage ranging from +2.7 V to +5.5 V or a dual supply of ±2.7 V. It incorporates volatile memory to retain resistance settings during operation and features a power-on midscale preset function. The nominal terminal resistance is 10 kΩ with a temperature coefficient of 700 ppm/°C.

Feature Summary

• Quad-channel architecture with 256 independent programmable positions
• SPI-compatible 3-wire serial interface with daisy-chain capability via SDO pin
• +2.7 V to +5.5 V single-supply or ±2.7 V dual-supply operation
• Power-on midscale preset and hardware reset (PR) pin functionality

Applications

• Mechanical potentiometer replacement in embedded systems
• Instrumentation gain and offset adjustment circuits
• Programmable voltage-to-current conversion stages
• Adjustable filters, delays, and time constant networks
• Line impedance matching applications

Procurement Notes

Verify the ordering suffix REEL7 confirms tape-and-reel packaging containing 1000 units. Confirm the BRUZ designation corresponds to the 24-lead TSSOP package variant. Ensure the final digit '10' matches the required 10 kΩ terminal resistance value for the specific circuit design requirements.

Selection Notes

Select this component when four independent variable resistors are required within a single package. The 10 kΩ resistance value suits moderate current applications compared to higher resistance variants. Verify that the system logic levels align with the specified input thresholds at the operating supply voltage. Consider the volatile memory nature if power loss retention is critical for the application.

Part Context

This part belongs to the AD5204 family of 4-channel digital potentiometers. It shares functional specifications with the AD5206, which offers six channels in the same package footprint. The BRUZ10 suffix specifically identifies the 10 kΩ resistance variant packaged in a 24-lead Thin Shrink Small Outline Package (TSSOP).

Replacement Considerations

The AD5204BRZ10-REEL serves as a direct pin-compatible alternative housed in a 24-lead SOIC package. Both variants share identical electrical characteristics and pinouts, differing only in the physical package dimensions and mounting style.
