Stereo, High-Power, Class D Amplifiers
MAX98400A/MAX98400B
General Description
The MAX98400A/MAX98400B Class D amplifiers provide
high-performance, thermally efficient amplifier solutions. The
MAX98400A delivers 2x20W into 8I loads or 1x40W into a
4I load. The MAX98400B delivers 2x12W into 8I loads.
An integrated limiting circuit prevents output clipping
distortion, protects small speakers from transient volt-
ages, and reduces power dissipation.
A thermal-foldback feature can be enabled to automati-
cally reduce the output power at above a junction tem-
perature of +120NC. 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 mini-
mizes noise coming into and out of shutdown.
The MAX98400A/MAX98400B are available in 36-pin
and 24-pin TQFN packages, respectively, and are speci-
fied over the -40NC to +85NC temperature range.
