EV7720DS-00A 9.5-24V Stereo Class D Single Ended Audio Amplifier Evaluation Board SOT23

The MPS EV7720DS-00A is an evaluation board built around the MP7720 for bench characterisation of the device in its intended topology. It operates from a 9.5 V to 24 V input. The board carries the device in its SOT23 package.

The EV7720DS-00A is the evaluation board for the MP7720, a mono 20W Class D Audio Amplifier.

Design Notes

The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
