MAX5435MEZT-T

Overview

The MAX5435MEZT-T is a single-channel digital potentiometer featuring 32 taps and an I²C interface. It offers a resistance value of 100k Ohms with linear taper characteristics. The device operates within a supply voltage range of 2.7V to 5.25V and utilizes non-volatile memory to retain wiper settings. Packaged in a TSOT-23-6 surface-mount case, it exhibits a typical temperature coefficient of 35ppm/°C and a tolerance of ±25%.

Feature Summary

• Non-volatile memory retains wiper position after power loss
• I²C serial interface for simplified control connections
• Linear taper characteristic for precise resistance adjustment

Applications

• Volume control in audio systems
• Gain adjustment in instrumentation circuits
• Voltage reference trimming
• System calibration and configuration

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated to ensure component authenticity. Check for lead-free compliance markings consistent with the '+' suffix if required by assembly specifications.

Selection Notes

Select this component for applications requiring persistent resistance settings without external battery backup. Ensure the system logic levels are compatible with the I²C interface requirements. Consider the 100k Ohm resistance range and ±25% tolerance against circuit precision needs before implementation.

Part Context

This part belongs to the MAX5435 series of 32-tap digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs. The TSOT-23-6 package allows for compact PCB layouts while maintaining reliable electrical performance across industrial temperature ranges.

Replacement Considerations

Direct substitutes include other 32-tap I²C digital potentiometers from Maxim Integrated such as the MAX5434 or MAX5436 series, provided pin compatibility and resistance values align with the design requirements.
