The MAX98400A/MAX98400B Class D amplifiers provide high-performance, thermally efficient amplifier solutions. The MAX98400A delivers 2x20W into 8Ω loads or 1x40W into a 4Ω load. The MAX98400B delivers 2x12W into 8Ω loads. 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 the output power at above a junction temperature of +120°C. Traditional thermal protection is also available in addition to robust overcurrent protection. The ICs operate from a single 8V to 28V supply and provide a high 67dB PSRR, eliminating the need for a regulated power supply. They offer up to 90% efficiency from a 12V supply. Filterless modulation allows the ICs to pass EN55022B EMI limits with 1m cables using only a low-cost ferrite bead and small-value capacitor on each output. Both devices feature eight-digitally-controlled gain settings. Comprehensive click-and-pop reduction circuitry minimizes noise coming into and out of shutdown. The MAX98400A/MAX98400B are available in 36-pin and 24-pin TQFN packages, respectively, and are specified over the -40°C to +85°C temperature range.
