Analog Devices - Model MAX4364 -Bridged Audio Power Amplifiers
Analog Devices offers ultralow jitter clock distribution products that fan out given signals for wireless infrastructure, instrumentation, broadband, ATE, and other applications demanding subpicosecond performance. Our clock products are ideal for clocking high performance analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). ADI clock ICs integrate PLL cores, dividers, phase offset, skew adjust, and clock drivers in small chip scale packages.
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.
