Detailed Description
MAX4364 contains MAX4364 high-power bridged amplifier, designed drive loudspeakers portable audio applications. MAX4364 operates from power supply that provide 2.7V 5.5V current. MAX4364 accept audio source inputs (IN) with peak-to-peak amplitudes VCC. audio source amplified drive 1.4W into speaker. MAX4364 positive negative differential outputs that 180° phase offset VCC/2. This allows voltage load peak voltage almost VCC. closed-loop gain MAX4364 configured 2V/V, reconfigured other gains. Refer Gain-Setting Resistors section MAX4364/MAX4365 data sheet. However, closed-loop gain reconfigured greater than feedback capacitor, added limit bandwidth, compensate stray capacitance inverting input.

Jumper Selection
Shutdown Jumper controls shutdown (SHDN) MAX4364. shutdown function activated MAX4364 installing shunt across pins JU1. shutdown function also controlled external source connected SHDN removing shunt (see Table shunt positions). Note: When measuring supply current shutdown mode, bias through resistor must taken into account. shutdown current calculated following equation: ISUPPLY IRES IMAX 4364 IRES
