The I²C interface sets the gain and volume in 64 steps, and the depop circuit suppresses the turn-on thump that otherwise couples through the speaker when the supply ramps. Mute and shutdown are also bus-controlled, so a single I²C transaction can silence the output or drop the quiescent current to near-zero for battery-powered standby. ## Supply rail and thermal design for the PCB The 4.5V minimum supply means the amplifier runs from a single-cell Li-ion battery down to its discharge cutoff; the 14V maximum covers a regulated 12V rail with margin. Short-circuit and thermal protection are on-die — the amplifier shuts down and auto-recovers when the fault clears, so a speaker terminal shorted to ground during assembly testing does not latch the part.","metaTitle":"MAX9768ETG+ Class D Amplifier, 10W Mono, Active","metaDescription":"Analog Devices MAX9768ETG+ Class D mono amplifier, 10W into 8Ω, 4.5-14V supply, I²C volume control, industrial temp.
