Analog Devices - Model MAX4364 -1.4W and 1W, Ultra-Small, Audio Power Amplifiers with Shutdown

SHARE

The MAX4364 is a high-performance, ultra-small audio power amplifier specifically designed for portable audio devices equipped with internal speakers. This amplifier delivers impressive output power, providing 1.4W from a 5V supply and 500mW from a 3V supply into an 8Ω load. Featuring a low total harmonic distortion plus noise (THD+N) of 0.04% at 1kHz and a high power supply rejection ratio (PSRR) of 68dB at 217Hz, the MAX4364 ensures superior audio clarity and minimal interference. Its efficient shutdown mode requires only 10nA of supply current, promoting energy conservation. The device includes internal DC bias generation, clickless operation, short-circuit, and thermal-overload protection to increase reliability. It operates stably in unity-gain configuration with gain set via two external resistors, making it versatile for various applications. Encased in an 8-pin SO package, the MAX4364's sleek design reduces external component count by eliminating the need for output-coupling capacitors.

The MAX4364/MAX4365 are bridged audio power amplifiers intended for portable audio devices with internal speakers. The MAX4364 is capable of delivering 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.

The MAX4364/MAX4365 bridged outputs eliminate the need for output-coupling capacitors, minimizing external 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.

The MAX4364 is available in a small 8-pin SO package. The MAX4365 is available in tiny 8-pin TDFN (3mm x 3mm x 0.8mm) and µMAX® packages.
