The 3 Ω figure is lower than the common 4 Ω or 8 Ω speaker impedance, so the amplifier delivers higher current per channel than a typical 8 Ω-rated part at the same supply voltage. Class AB topology means the output stage biases into conduction across the full waveform, avoiding the crossover distortion of Class B while running cooler than a pure Class A stage. The trade-off is quiescent current draw — budget the idle current into the 5 V rail when sizing the supply. ## Package and thermal interface 28-TSSOP with exposed pad (EP) — the die-attach paddle on the underside of the package must be soldered to a PCB copper plane to pull heat out of the 3 W output stage. Without a thermal via array under the pad, the junction temperature rises above the 85 °C ambient limit at full output. The exposed pad is the main thermal path — the plastic TSSOP body alone cannot dissipate the 2–3 W of heat from both channels driven simultaneously. Layout should connect the EP to a ground plane with at least four thermal vias.","metaTitle":"MAX9762EUI Class AB Audio Amp, 3W x 2 @ 3Ω, 28-TSSOP","metaDescription":"Active MAX9762EUI stereo audio amplifier, 3W per channel into 3Ω, 28-TSSOP-EP.

The base MAX9762 is available in other packages (e.g., 28-TQFN). Pin compatibility depends on the specific package — the TSSOP-EP footprint differs from the TQFN, so a board layout change is required when swapping between package options."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX9762EUI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX9762EUI when reusing this data.
