AUD4988

The AUD4988 is a 3D stereo audio power amplifier essentially designed for communication purpose such as mobile phone and other portable devices. It can deliver 2 watt, per channel, of continuous average power to an 4 Ohm BTL load. There is less than 1% distortion from a 5V DC power supply.

The AUD4988 were specifically designed to provide high quality output power with a minimal amount of external components. It requires no output coupling capacitors, for this reason, it is perfectly meet the needs of mobile phone and other low voltage applications where require the consumption of power in the smallest amount.

The AUD4988 add a selectable 3D Stereowide Function to provide the 3D stereo imaging effect. The 3D Stereowide function can be adjusted by the external capacitor to meet user requirement.

To optimize the external components, AUD4988 built-in the gain network with preset gain (Av = 2, 2.8, 4, 5.6 & 8). The AUD 4988 allows shutdown control on the device, if shutdown control pin is being driven to logic low, a low power consumption shutdown mode will be activated. Additionally, the AUD4988 features an internal thermal shutdown protection mechanism.

The AUD4988 has an advanced pop & click circuitry that eliminates the noise during turning on and turning off of the device.
