MAX5486EUG+

Audio Special Purpose Overview

The MAX5486EUG+ is a dual-channel digital volume control IC featuring a debounced pushbutton interface for audio applications. It provides logarithmic taper volume and balance control with 32 log-spaced tap points per channel, replacing mechanical potentiometers. The device operates on a single +2.7V to +5.5V supply or dual ±2.7V supplies. Key electrical parameters include a nominal 40kΩ end-to-end resistance, typical THD+N of 0.003%, and mute attenuation of -90dB. It integrates a bias generator eliminating external op-amps, click-and-pop suppression, and five-segment LED indicators.

Audio Special Purpose Feature Summary

• Debounced pushbutton interface with SmartWiper™ auto-advance (4Hz/8Hz/11Hz rates)
• Dual 40kΩ logarithmic taper pots with 32 tap positions and buffered wiper outputs
• Integrated bias generator providing (VDD + VSS)/2 reference voltage
• Click-and-pop suppression minimizes audible noise during wiper transitions

Audio Special Purpose Applications

• Home-theater speakers
• Desktop speakers
• Portable media players
• Docking stations

Audio Special Purpose Procurement Notes

Verify the component is the lead-free/RoHS-compliant variant indicated by the '+' suffix in MAX5486EUG+. Confirm the package is 24-TSSOP and the temperature range matches the specific grade required (-40°C to +85°C or +125°C). Check datasheet revision history for any functional updates.

Audio Special Purpose Selection Notes

Select this part for stereo audio systems requiring direct pushbutton control without microcomputer intervention. Ensure logic supply voltage (VLOGIC) is compatible with the system's control signals (2.7V to VDD). Verify that the 40kΩ impedance matches the source and load requirements to maintain the specified 0.003% THD+N performance.

Audio Special Purpose Part Context

The MAX5486 belongs to Maxim Integrated's family of digital potentiometer and volume control ICs. It is designed specifically as a replacement for mechanical volume controls in consumer audio equipment. The EUG+ designation indicates the 24-pin TSSOP package with RoHS compliance.
