AD5232BRU10-REEL7

Digital Potentiometers Overview

The AD5232BRU10-REEL7 is a dual-channel, nonvolatile digital potentiometer featuring 256-position resolution and 10 kΩ nominal terminal resistance. It operates on a single supply of 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 power-on preset, plus 14 bytes of user-accessible nonvolatile memory. It utilizes an SPI-compatible serial interface with readback capability and maintains wiper settings via permanent memory write protection.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256 tap positions per channel
• Nonvolatile EEMEM storage with 100-year typical data retention
• SPI-compatible serial interface supporting daisy-chaining
• Hardware Preset (PR) pin for automatic power-on reset to stored values

Digital Potentiometers Applications

• Mechanical potentiometer replacement in solid-state designs
• Instrumentation gain and offset adjustment circuits
• Programmable voltage-to-current conversion stages
• Sensor calibration and programmable filter time constants

Digital Potentiometers Procurement Notes

Verify the specific suffix '10' confirms the 10 kΩ resistance variant, as the base AD5232 family includes 50 kΩ and 100 kΩ options. Confirm RoHS compliance status for the REEL7 packaging configuration against current manufacturing records. Ensure the source document matches the Rev C datasheet specifications for electrical characteristics.

Digital Potentiometers Selection Notes

Select this component when dual-channel variable resistance with persistent state is required without external memory. The 10 kΩ value suits moderate impedance applications; higher resistance variants are available if lower bias currents are needed. Verify that the system voltage falls within the 2.7 V to 5.5 V single-supply range or ±2.25 V to ±2.75 V dual-supply range.

Digital Potentiometers Part Context

This part belongs to the AD523x family of nonvolatile digital potentiometers, which also includes the single-channel AD5231 and quad-channel AD5233. The BRU package designation indicates a 16-lead TSSOP surface-mount housing. The REEL7 suffix specifies tape-and-reel packaging for automated assembly processes.

Digital Potentiometers Replacement Considerations

Direct functional substitutes include the AD5232BRZ-10 for leaded versions or other 10 kΩ variants within the AD5232 series. Cross-model replacements like the AD5231 offer single-channel functionality in a similar package.
