概觀

The IS31AP4833 is a treble and bass control with 3D enhancement audio power driver. The IS31AP4833 provides tone (bass and treble) controls and volume control as well as a stereo audio power amplifier capable of delivering 2.8W into 4Ω with less than 10% THD with a 5V supply. The IS31AP4833 uses flexible I2C control interface for multiple application requirements. It also features 3D sound circuitry which can be externally adjusted via a simple RC network. The IS31AP4833 features a 13 steps tone control (-12dB ~ +12dB, 2dB/step) and a 29 steps volume control (mute, -42dB ~ +12dB, 2dB/step) for the headphone and stereo outputs. The volume and tone are controlled through an I2C compatible interface. The IS31AP4833 can get independent volume control for two channels. IS31AP4833 is available in QFN-36 (4mm × 4mm) and TQFP-48(7mm × 7mm) package. It operates from 3.0V to 5.5V over the temperature range of -40°C to +85°C.
