Overview

Description

The MAX20331/MAX20331A are overvoltage ICs designed to protect the audio codecs and electronics of portable devices. Connecting the MAX20331/MAX20331A between the 3.5mm jack and audio path electronics provides protection against high-voltage conditions to ±40V.

The MAX20331/MAX20331A are available in a space-saving, 9-bump, 0.4mm pitch, 1.23mm x 1.23mm wafer-level package (WLP) and operate over the -40°C to +85°C extended temperature range.
