IS31AP4832

IS31AP4832 DUAL 2.5W AUDIO POWER AMPLIFIER AND STEREO HEADPHONE DRIVER WITH TONE CONTROL AND 3D ENHANCEMENT January 2012 GENERAL DESCRIPTION The IS31AP4832 is a monolithic integrated circuit that provides tone (bass and treble) controls as well as a stereo audio power amplifier capable of delivering 2.5W (Typ.) into 4Ω or 1.7W (Typ.) into 8Ω with less than 10% THD with a 5V supply. The IS31AP4832 uses flexible I2C control interface for multiple application requirements. The IS31AP4832 also features 3D sound circuitry which can be externally adjusted via a simple RC network. The headphone amplifier features Output Capacitor-less (OCL) architecture that eliminates the output coupling capacitors required by traditional headphone amplifiers. The IS31AP4832 features a 13 step tone control for the headphone and stereo outputs. The device mode select and Tone are controlled through an I2C compatible interface. Thermal shutdown protection prevents the device from being damaged during fault conditions. Superior click and pop suppression eliminates audible transients on power-up/down and during shutdown.
