Product details

330mW mono amp in a SOT-23-8 — what the ratings mean on the bench

The MAX4367EKA-T is a Class AB audio power amplifier delivering 330mW into a 16Ω load from a single channel (mono). That 330mW figure is the max output at 1% THD+N typical — enough to drive a small speaker or earpiece in a portable device where battery life matters more than concert volume. Supply range runs from 2.3V to 5.5V, so it works directly off a single Li-ion cell (3.6V nominal) or a regulated 3.3V/5V rail without needing a separate audio supply. The shutdown pin (part of the part's function per the description) lets the MCU kill the output stage when idle, cutting quiescent current to near-zero.

Package, temperature grade, and rework reality

Housed in an SOT-23-8 (supplier device package same as the case code), this is a 8-lead surface-mount package with a 0.65mm pitch typical for the family.

Frequently asked questions

What is the output power of MAX4367EKA-T into a typical speaker load?

It delivers 330mW per channel into a 16Ω load (mono). That is the max output power at the rated distortion — suitable for portable speakers, headphone drivers, or audio alert circuits where the load impedance is in the 8Ω–32Ω range.

What package does MAX4367EKA-T come in, and is it reworkable by hand?

It comes in an SOT-23-8 surface-mount package. The 0.65mm lead pitch and exposed die-attach pad are manageable with a hot-air station — the part is small but the leads are visible under a stereo microscope, so rework is feasible without a dedicated reflow oven.
