TPA6020A2 

Stereo full differential Class AB audio amplifier

illustrate   The TPA6020A2 is a 2.8 W stereo bridged load (BTL) amplifier designed to drive at least 3 stereo speakers – impedance. The device operates from 2.5 V to 5.5 V and draws only 8 quiescent supply currents. The internal feedback resistor makes the gain only two, and the input resistor is set for each channel. The amplifier's fully differential architecture performs with -80 dB power suppression from 20 Hz to 2 kHz, improves RF rectification immunity, small printed circuit board area, and fast boot times with minimal pop, making it ideal for laptop applications TPA6020A2.   characteristic   Ideal for laptops The fully differential structure and high PSRR (-80 dB) provide excellent RF rectification immunity 2.8 W3 from a 5 V supply at total harmonic distortion = 10% (typical). Very low crosstalk: -100 dB at 5 V, 3 typical 2.5 - V to 5.5 V operating range Low supply current: 8 mAh 5 typical V Shutdown Current: 80 - nA typical Fast start (27 ms) with minimal pop The number of internal feedback resistor elements is reduced Thermally enhanced QFN package apply laptop LCD TV
