EV7740DN-01B 9.5-36V Stereo Class D Single Ended Audio Amplifier Evaluation Board SOIC8E

The MPS EV7740DN-01B is an evaluation board built around the MP7740 for bench characterisation of the device in its intended topology. It operates from a 9.5 V to 36 V input. The board carries the device in its SOIC8E package.

The EV7740DN-01B is the evaluation board for the MP7740, a stereo 15W 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.
