The TS4909 is a stereo audio amplifier designed to drive headphones in portable applications. The integrated phantom ground is a circuit topology that eliminates the heavy output coupling capacitors. This is of primary importance in portable applications where space constraints are very high. A sing • No output coupling capacitors necessary \n• Pop-and-click noise reduction circuitry \n• Operating from VCC = 2.2 V to 5.5 V \n• Standby mode active low \n• Output power: \n •158 mW at 5 V, into 16 Ω with 1% THD+N max (1 kHz) \n •52 mW at 3.0 V into 16 Ω with 1% THD+N max (1 kHz) \n• Ultra-;
