AD5233BRUZ100-R7

Digital Potentiometers Overview

The AD5233BRUZ100-R7 is a quad-channel, nonvolatile digitally controlled potentiometer (DigiPOT) from Analog Devices. It features four independent 6-bit resolution wipers with 64 tap positions and a nominal terminal resistance of 100 kΩ. The device integrates EEPROM for persistent storage of wiper settings, enabling automatic power-on restoration within approximately 140 μs. It operates on a single supply voltage ranging from 2.7 V to 5.5 V or dual supplies of ±2.5 V. Communication is handled via an SPI-compatible serial interface supporting readback and daisy-chaining capabilities.

Digital Potentiometers Feature Summary

• Quad-channel architecture with 64-position (6-bit) resolution per channel
• Nonvolatile memory (EEMEM) retains wiper settings across power cycles
• SPI-compatible serial interface with data readback functionality
• Supports linear increment/decrement and ±6 dB/step logarithmic adjustment commands

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 '-R7' against the manufacturer's official ordering guide to confirm tape and reel packaging specifications. Ensure the 100 kΩ resistance value matches the design requirements, as other variants exist. Confirm RoHS compliance status through current datasheet documentation prior to procurement.

Digital Potentiometers Selection Notes

Select this component when nonvolatile retention of analog settings is required without external memory controllers. The 100 kΩ terminal resistance offers a balance between noise performance and drive capability. Verify that the system voltage remains within the 2.7 V to 5.5 V range and that the SPI timing parameters align with the microcontroller interface.

Digital Potentiometers Part Context

This part belongs to the AD5233 family of quad DigiPOTs. The 'B' indicates the industrial temperature grade (-40°C to +85°C), 'RUZ' denotes the 24-lead TSSOP package, and '100' specifies the 100 kΩ resistor value. The '-R7' suffix typically indicates reel packaging for surface-mount assembly.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include the AD5233BRU100 (tube packaging). For applications requiring higher resolution, consider the AD5232 (8-bit) or AD5231 (10-bit) series, though pin counts and interfaces may differ.
