Device identity and output capability
The MAX4367EKA: The mono output stage is designed for portable audio applications where the supply voltage is limited to a single lithium-ion cell or regulated 3.3 V / 5 V bus — the 330 mW figure at 16 Ω is the typical maximum before clipping into that impedance.
Package and temperature range
Housed in an 8-lead SOT-23 surface-mount package, the MAX4367EKA occupies minimal board area and suits compact portable designs where the amplifier sits near the audio jack or speaker connector.
