November 2005...Monolithic
Power Systems (MPS) is now shipping the MP7722, an ultra
compact 2 x 20W Class D audio amplifier.
Delivering 20W into 4W (10% THD) and integrating four 180mW MOSFETs,
it achieves 93% efficiency at full output power. The MP7722 features
a unique closed loop topology that provides excellent linearity
with a very low THD+N of 0.06% at 1kHz, while the Company’s
proprietary variable switching frequency topology reduces the magnitude
of EMI spikes during operation. Other features include adjustable
gain via two external resistors, power-on/off pop & click suppression,
and thermal/short-circuit protection. In addition, the amplifier
incorporates mute and standby modes for lower power consumption.
Available in a small TSSOP package, the MP7722 is the most compact
solution in its class.
