1.4W and 1W, Ultra-Small, Audio Power

Amplifiers with Shutdown

General Description

Features

The MAX4364/MAX4365 are bridged audio power

amplifiers intended for portable audio devices with

internal speakers. The MAX4364 is capable of deliver-

ing 1.4W from a single 5V supply and 500mW from a

single 3V supply into an 8Ω load. The MAX4365 is

capable of delivering 1W from a single 5V supply and

450mW from a single 3V supply into an 8Ω load. The

MAX4364/MAX4365 feature 0.04% THD + N at 1kHz,

68dB PSRR at 217Hz and only 10nA of supply current

in shutdown mode.

ꢀ 1.4W into 8Ω Load (MAX4364)

ꢀ 1W into 8Ω Load (MAX4365)

ꢀ 0.04% THD + N at 1kHz

ꢀ 68dB PSRR at 217Hz

ꢀ 2.7V to 5.5V Single-Supply Operation

ꢀ 5mA Supply Current

ꢀ Low-Power, 10nA Shutdown Mode

The MAX4364/MAX4365 bridged outputs eliminate the

need for output-coupling capacitors, minimizing exter-

nal component count. The MAX4364/MAX4365 also

include internal DC bias generation, clickless operation,

short-circuit and thermal-overload protection. Both

devices are unity-gain stable, with the gain set by two

external resistors.

ꢀ Pin Compatible with the LM4861/LM4862/LM4864

(MAX4364)

ꢀ Clickless Power-Up and Shutdown

ꢀ Thermal-Overload and Short-Circuit Protection

ꢀ Available in Thin QFN, µMAX, and SO Packages

The MAX4364 is available in a small 8-pin SO package.

The MAX4365 is available in tiny 8-pin thin QFN

(3mm ✕ 3mm ✕ 0.8mm) and µMAX packages.
