PT5301 : The PT5301 is an audio power amplifier mainly designed for applications in mobile phones and other portable communication device applications. It is capable of delivering 1.25 watts of continuous average power to an 8Ω load and 2 watts of continuous average power to a 4Ω load with less than 1% distortion (THD+N) from a 5V power supply. The PT5301 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. The PT5301 features a low-power shutdown mode and improved pop & click circuitry that attenuates noise which would otherwise occur during tu.
PT5303 : The PT5303 is a fully differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.25W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V power supply. The PT5303 is designed specifically to provide high quality output power with a minimal amount of external components. The PT5303 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phones and other low voltage applications where minimal power consumption is a primary requirement. The PT5303 contains advanced pop & click ci.
