Maxim MAX98400AETX+T

Класс D2-канальный (стерео)8 В ~ 28 В

Overview

The MAX98400AETX+ is a stereo, high power class D amplifier in 36 pin TQFN package. This amplifier provides high performance and thermally efficient amplifier solutions. The MAX98400A delivers 2x20W into 8ohm loads or 1x40W into a 4ohm load. An integrated limiting circuit prevents output clipping distortion, protects small speakers from transient voltages and reduces power dissipation. A thermal foldback feature can be enabled to automatically reduce output power at above a junction temperature of +120°C. Traditional thermal protection is also available in addition to robust overcurrent protection. The device operates from a single 8V to 28V supply by eliminating the need for regulated power supply. Filterless modulation allows the MAX98400A to pass EN55022B EMI limits with 1m cables using only a low cost ferrite bead and small value capacitor on each output. Comprehensive click and pop reduction circuitry minimizes noise coming into and out of shutdown.
