DESCRIPTION
The MP1720 is a high efficiency Class-D audio
amplifier. It utilizes a full bridge output structure
capable of delivering 2.7W into 4 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:
250m 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.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/
JA
. Exceeding the maximum allowable powe
r
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operation conditions.
4) Measured on JESD51-7, 4-layer PCB.
