Low-EMI High-Efficiency Audio Amplifier
MPS CONFIDENTIAL AND PROPRIETARY INFORMATION – INTERNAL USE ONLY
DESCRIPTION
FEATURES
The MP1720 is a high efficiency Class-D audio
amplifier. It utilizes a full bridge output structure
capable of delivering 2.7W into 4Ω speaker.
This device exhibits the high fidelity of a class
AB amplifier with an efficiency of 90% which
dramatically reduces solution size by integrating
the following:
 250mΩ power MOSFETs (V_IN =3.3V)
 Startup / Shutdown pop elimination
 Short circuit /Thermal overload Protection
The MP1720 features a pin-selectable 1MHz or
1.3MHz frequency control or can be
synchronized to an external clock source. The
flexible switching frequency and internal EMI-
reduction scheme eliminates the need for an
output LC filter and passes emission standards
without filter & with considerable cable.
The MP1720 has five fixed gain options.
MP1720-3: 3dB; MP1720-6: 6dB; MP1720-9:
9dB; MP1720-12: 12dB; MP1720-216: 21.6dB.
The MP1720 is available in 10-pin MSOP-EP
and 10-pin QFN packages.
