AD5233BRUZ50-R7

Digital Potentiometers Overview

The AD5233BRUZ50-R7 is a quad-channel, nonvolatile memory digital potentiometer with 64-position resolution. It features a 10 kΩ nominal terminal resistance and operates on a single supply of 2.7 V to 5.5 V or dual supplies of ±2.5 V. The device includes an SPI-compatible serial interface for wiper setting control and readback. Each channel retains its position in embedded EEMEM, which restores automatically upon power-up within 140 μs typical. The component provides 11 bytes of extra user-defined nonvolatile memory and supports permanent write protection via the WP pin.

Digital Potentiometers Feature Summary

• Quad-channel architecture with 6-bit (64-position) resolution per channel

• Sensor calibration

Digital Potentiometers Procurement Notes

Verify the specific suffix -R7 indicates tape and reel packaging when sourcing. Confirm the BRUZ designation corresponds to the industrial temperature range (-40°C to +85°C) and TSSOP-24 package. Check current availability status as distribution channels may vary for this specific resistor value variant.

Digital Potentiometers Selection Notes

Select this model for applications requiring four independent programmable resistors with persistent settings. Ensure the system logic levels are compatible with the SPI interface at the operating voltage. Verify that the 10 kΩ resistance value fits the circuit's current and voltage constraints, noting the wiper resistance varies with code.

Digital Potentiometers Part Context

This part belongs to the AD5233 family of quad digital potentiometers. The 'B' grade specifies tighter performance tolerances compared to the 'A' grade. The 'U' indicates the TSSOP package, while 'Z' denotes lead-free composition. The '50' suffix identifies the 10 kΩ terminal resistance option among available 10 kΩ, 50 kΩ, and 100 kΩ variants.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include other AD5233 variants with different resistance values (e.g., AD5233BRUZ10, AD5233BRUZ100). Cross-family replacements require verification of pinout compatibility and electrical parameter alignment.
