AUD5999 2 Watt Ultra Small Audio Power Amplifier with Shutdown General Description
Key Specifications
The AUD5999 is an audio power amplifier for mobile phone and other portable electronic device applications. It can deliver 1.3 watts of continuous average power to an 8 ohm BTL (bridge tied load) and 2 watts of continuous average power to a 4 ohm BTL, with less than 1% distortion from a 5V DC power supply.
The AUD5999 is specifically designed to provide high output power with a minimal amount of external components. It requires no output coupling capacitors, for instance. Because of its space-saving footprint, it perfectly meets the needs of mobile phones, PDAs, notebook computers and other low-voltage applications that require small power sources in a small package.
Features Ultra Small Package Size Space Saving Thermal Package External Gain Configuration Stable Unity Gain Can Drive CL up to 200pF
The AUD5999 can offer a low standby current and a zero shutdown current. Furthermore, the amplifier’s startup time is fast enough to use its shutdown mode as a mute function.
Applications Mobile Phones PDAs Notebook Computers Portable Electronic Devices
The AUD5999 features circuitry that eliminates pop-and-click noise whenever the device is turned on or off.

Shutdown Control In order to reduce the power consumption while device is not in use, there is shutdown circuitry employed to switch off the amplifier bias of each channel. By applying a logic low signal to shutdown pin of selected channel, the related bias circuitry will be switched off to minimize the current draw. While the device may be disabled with shutdown voltages in between ground and supply, the idle current may be greater than the typical value. To avoid unwanted state changes, the shutdown pin should be tied to a definite voltage. In many applications, output signal from a microcontroller is used to control the shutdown circuitry, which provides a quick, smooth transition to shutdown. Another solution is to use a single-throw switch in conjunction with an external resistor (pull-up or pull-down, depending on shutdown mode selection). This scheme guarantees that the shutdown pin will not float, thus preventing unwanted state changes. Selection of External Components The external components will be the one of the important factor to affect the amplifier performance, proper selection on them will allow system function in more efficiency way. The AUD5999 should be used in low gain configurations to minimize THD+N values, and maximize the signal to noise ratio. Besides gain, another major consideration in system performance is the closed loop bandwidth of the amplifier. To a large extent, the bandwidth is dictated by the choice of external components. The input coupling capacitor forms a first order high pass filter, which limits low frequency response, and should be chosen based on needed frequency response for a few distinct reasons. In many cases the speakers used in portable systems, whether internal or external, have little ability to reproduce signals below 100Hz to 150Hz. Thus, using a large input capacitor may not increase actual system performance. Besides minimizing the input capacitor size, careful consideration should be paid to the bypass capacitor value. It will determine how fast the chip turns on.
