Class D amplifiers integrate anticlipping, voltage limiting

Sunnyvale, Calif.— Maxim Integrated Products has introduced the MAX98400, a family of filterless Class D amplifiers available in 2 x 12W, 2 x 20W, and 1 x 40W configurations.

Anticlipping circuitry avoids clipping by automatically reducing the amplifier's gain when the supply voltage in insufficient to deliver the desired output voltage. Voltage limiting prevents damage when the supply voltage outputs more power than the speaker can handle. A pin-selectable mono/stereo mode changes the MAX98400A from a stereo 20W to mono 40W amplifier, while the MAX98400B is a stereo 12W amplifier.

Applications include TVs, notebooks, and all-in-one desktop applications. 

The MAX98400 amplifiers are fully specified over the -40ºC to +85ºC extended temperature range. The MAX98400A is packaged in a small, 6mm x 6mm, lead-free, 36-pin TQFN and the MAX98400B in a 4mm x 4mm, 24-pin TQFN.

Prices start at $1.20 for the MAX98400A and $0.95 for the MAX98400B (1000-up, FOB USA).
