Product details

Class AB stereo headphone driver with DirectDrive®

The MAX9820ETB+T is a Class AB stereo headphone amplifier from Analog Devices' DirectDrive® series, delivering 95mW per channel into a 32Ω load. The output is a 2-channel (stereo) headphone drive, with integrated depop circuitry to suppress click-and-pop on startup and shutdown.

Package, footprint, and protection

Housed in a 10-WFDFN with exposed pad (3x3mm body, supplier package 10-TDFN), the part is surface-mount and requires a thermal pad for adequate heat sinking during continuous output. On-chip short-circuit and thermal protection prevent damage under fault conditions; the shutdown feature reduces quiescent current to near-zero when the amplifier is not in use.

Lifecycle and compliance

Supplied in tape-and-reel (TR) or cut-tape (CT) packaging, suitable for both prototyping and volume assembly.
