AD5232BRUZ100

Digital Potentiometers Overview

The AD5232BRUZ100 is a dual-channel, nonvolatile digital potentiometer featuring 256-position resolution and a nominal terminal resistance of 100 kΩ. It operates on a single supply from 2.7 V to 5.5 V or a dual supply of ±2.25 V to ±2.75 V. The device includes two RDAC registers and corresponding EEMEM registers for wiper position storage, alongside 14 bytes of general-purpose user EEMEM. It utilizes an SPI-compatible serial interface for control and readback.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact resistance value and package configuration. Ensure compatibility with system voltage requirements, as the device supports both single-supply (2.7 V to 5.5 V) and dual-supply operation.

Digital Potentiometers Selection Notes

Select this component when a dual-channel solution with persistent settings is required. The 100 kΩ resistance value suits applications needing higher impedance levels. Consider the 16-lead TSSOP package dimensions for PCB layout constraints and verify that the SPI interface timing aligns with the microcontroller capabilities.

Digital Potentiometers Part Context

This part belongs to the AD5232 family of nonvolatile digital potentiometers. The BRUZ suffix indicates a commercial temperature range variant in a 16-lead TSSOP package. The '100' designation specifies the 100 kΩ nominal end-to-end resistance, distinguishing it from 10 kΩ and 50 kΩ variants within the same series.

Digital Potentiometers Replacement Considerations

Direct replacements include other AD5232 variants with different resistance values (e.g., AD5232BRUZ10 for 10 kΩ or AD5232BRUZ50 for 50 kΩ), provided the resistance tolerance and pinout remain compatible with the existing design.
