The Class D switching topology keeps quiescent losses low, so the 32-TQFN (5x5) package with exposed pad handles the thermal load without forced air in most installations. On-chip short-circuit and thermal protection, plus a mute function and shutdown input, give the system designer a clean supervisory interface. The differential inputs reject ground noise picked up over long signal runs — useful in automotive infotainment or distributed audio where the amplifier sits remote from the source. ## Supply range and temperature grade Rated for -40 °C to 85 °C ambient, the MAX9703ETJ+T suits outdoor telecom enclosures, automotive cabin audio, and industrial panel speakers. ## Package and thermal management The 32-TQFN (5x5 mm) with exposed pad demands a thermal land on the PCB — a via array under the pad to a ground plane is the standard approach. ## Lifecycle and sourcing Marked as Active by the manufacturer and ROHS3 compliant. No official second source or pin-compatible alternate is listed in the available documentation; the MAX9703ETJ+T is a Maxim-only footprint.","metaTitle":"MAX9703ETJ+T Class D Audio Amp, 18W Mono, 32-TQFN","metaDescription":"Maxim Integrated MAX9703ETJ+T Class D mono amplifier delivers 18W into 16Ω.
