MAX38886ATD+

Overview

The MAX38886ATD+ is a high-performance, low-power, dual-channel analog switch manufactured by Analog Devices Inc. (Maxim Integrated). It operates with a single supply voltage ranging from 2.7V to 5.5V or split supplies of ±1.35V to ±2.75V. The device features ultra-low on-resistance and excellent signal integrity, making it suitable for precision data acquisition systems. Key electrical characteristics include a typical on-resistance of 4Ω and an on-resistance match of 0.05Ω across channels.

Feature Summary

• Ultra-low on-resistance ensures minimal signal attenuation in precision analog paths.
• Low power consumption supports battery-operated and portable applications.
• High breakdown voltage protects internal circuitry during overvoltage events.

Applications

• Portable medical instrumentation
• Data acquisition systems
• Audio switching circuits

Procurement Notes

Verify the specific suffix 'ATD+' indicates the standard commercial temperature range and lead-free compliance. Confirm the package type matches the TD (TDFN) footprint requirements for your PCB layout. Ensure the manufacturer documentation aligns with the current product lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when low distortion and high bandwidth are critical for signal fidelity. Consider the operating voltage range to ensure compatibility with system power rails. Evaluate the thermal performance within the TDFN package if high ambient temperatures are expected in the application environment.

Part Context

This part belongs to Maxim Integrated's family of low-voltage analog switches designed for space-constrained designs. It offers improved performance over previous generations regarding on-resistance flatness and leakage current. The TDFN package provides a compact solution for modern miniaturized electronic devices requiring reliable analog signal routing.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family that may offer updated packaging or extended temperature ranges. Verify functional equivalence regarding on-resistance and bandwidth specifications before substituting with parts from other manufacturers.
