AD5232BRUZ100-RL7

Digital Potentiometers Overview

The AD5232BRUZ100-RL7 is a dual-channel, nonvolatile digital potentiometer featuring 256-position (8-bit) resolution and a nominal terminal resistance of 100 kΩ. 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 persistent wiper settings, plus 14 bytes of general-purpose user EEPROM. Communication is handled via an SPI-compatible serial interface. Key electrical parameters include a typical power supply current of 3.5 µA, a maximum resistor tolerance of +20%, and an operating temperature range from −40°C to +85°C.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256-tap resolution and 100 kΩ nominal resistance.
• Nonvolatile memory retains wiper positions across power cycles with 100-year typical data retention.
• SPI-compatible serial interface supporting daisy-chaining and readback of internal registers.
• Includes 14 bytes of general-purpose user EEPROM for constant data storage.

Digital Potentiometers Applications

• Mechanical potentiometer replacement in solid-state designs
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion circuits
• Sensor calibration systems

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm that the component meets RoHS compliance requirements for the intended market. Check for any end-of-life notices or obsolescence warnings associated with this part number before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when a dual-channel digital solution with nonvolatile memory is required. Ensure the system voltage falls within the 2.7 V to 5.5 V single-supply range. Verify that the 100 kΩ resistance value aligns with the circuit's impedance requirements. Consider the TSSOP-16 package dimensions for PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the AD5232 family of dual-channel digital potentiometers. The 'BRU' designation indicates the commercial temperature grade (-40°C to +85°C) and TSSOP-16 package. The 'Z100' specifies the 100 kΩ resistance value, while '-RL7' denotes the reel packaging format used for surface-mount assembly.

Digital Potentiometers Replacement Considerations

Direct pin-for-pin replacements within the same family include other resistance variants such as the AD5232BRUZ50-RL7 (50 kΩ) or AD5232BRUZ10-RL7 (10 kΩ). Ensure that any substitute maintains the same SPI interface protocol and nonvolatile memory functionality if power-cycle retention is critical.
