The Future of Analog IC Technology
DESCRIPTION
The MPQ7731 is a mono, 5W - 30W Class D
Audio Amplifier. It is one of MPS’ second
generation of fully integrated audio amplifiers which
dramatically reduces solution size by integrating
the following:
Start Up / Shut Down Pop Elimination
Short Circuit Protection Circuits
180m Power MOSFETs
Mute / Standby Mode
The MPQ7731 utilizes a full bridge output
structure capable of delivering 5W - 30W into
4 speakers. As in all other MPS Class D
Audio Amplifiers, this device exhibits the high
fidelity of a Class AB amplifier with an efficiency
of 90%. The circuit is based on the MPS’
proprietary variable frequency topology Analog
Adaptive Modulation (AAM, Patent No.
6,420,930; other patents pending) that delivers
excellent PSRR, fast response time and
operates on a single power supply.

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
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
