EV7770-F-00B 9.5-36V Mono Bridge Tied Load Class D Audio Amplifier Evaluation Board

EV7770-F-00B 9.5-36V Mono Bridge Tied Load Class D Audio Amplifier Evaluation Board

The EV7770-F-00B is the BTL (Bridge Tied Load) configuration evaluation board for the MP7770GF, which can deliver 90W into 8Ω speaker under 36V VDD.

Key Specifications

Features

• 90W Output at VDD = 32V into a 6Ω load, 10% THD
• 90W Output at VDD = 36V into a 8Ω load, 10%THD
• THD+N = 0.04% at 1W, 8Ω, 1kHz
• 95% Efficiency at 90W and VDD=36V with 8Ω load
• Low Noise (120µV Typical)
• 9.5V to 36V Operation from a Single Supply

Evaluation Board

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.
