miniAMP

miniAMP

miniAMP is a digital amplifier module designed for low power, high efficiency, stereo or multi-channel applications. Configured in Bridge Tied Load (BTL, differential drive) for stereo mode (2x20W), for 4 channels (4x10W) in Single Ended (SE) or an Hybrid configuration for 2.1ch mode (2ch SE + 1 ch BTL).

This credit size amplifier module will stand out from the Class D crowd with its closed loop power stage architecture. Among the many advantages of such architecture, a higher Power Supply Rejection Ratio (PSRR) of up to 60dB, lessens the impact of power supply noise on audio quality. The higher damping factor of closed loop power stage also provides better control of speaker cone movement, especially at low frequency. All together, superior audio performance that one would not expect from such tiny amplifier.

Finally, designed with flexibility in mind, this module can easily be configured to meet your customization needs with a simple jumper configuration. Combined with miniDIGI and miniDSP, building DSP
powered all digital multi-channel amplifiers couldn't be easier!
