Maxim

Part Description: MAX4364 65 DS


Part Details:

19-2387; Rev 3; 11/05 1.4W and 1W, Ultra-Small, Audio Power Amplifiers with Shutdown MAX4364/MAX4365 General Description Features The MAX4364/MAX4365 are bridged audio power 1.4W into 8 Load (MAX4364) amplifiers intended for portable audio devices withinternal speakers. The MAX4364 is capable of deliver- 1W into 8 Load (MAX4365) ing 1.4W from a single 5V supply and 500mW from a 0.04% THD+N at 1kHz single 3V supply into an 8 load. The MAX4365 iscapable of delivering 1W from a single 5V supply and 68dB PSRR at 217Hz 450mW from a single 3V supply into an 8 load. The 2.7V to 5.5V Single-Supply Operation MAX4364/MAX4365 feature 0.04% THD+N at 1kHz,68dB PSRR at 217Hz, and only 10nA of supply current 5mA Supply Current in shutdown mode. Low-Power, 10nA Shutdown Mode The MAX4364/MAX4365 bridged outputs eliminate the Pin Compatible with the LM4861/LM4862/LM4864 need for output-coupling capacitors, minimizing exter-nal component count. The MAX4364/MAX4365 also (MAX4364) include internal DC bias generation, clickless operation, Clickless Power-Up and Shutdown short-circuit and thermal-overload protection. Bothdevices are unity-gain stable, with the gain set by two Thermal-Overload and Short-Circuit Protection external resistors. Available in TDFN, µMAX, and SO Packages The MAX4364 is available in a small 8-pin SO package.The MAX4365 is available in tiny 8-pin TDFN (3mm Ordering Information 3mm 0.8mm) and µMAX® packages.
