General Description:

The AF4871A is a bridge-connected audio power amplifier capable of delivering typically 1.1W of continuous average power to an 8W load with 0.5% (THD) from a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the AF4871A does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optionally suited for low-power portable systems. The AF4871A features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable AF4871A can be configured by external gain-setting resistors.

Features:

■ THD at 1 kHz at 1W continuous

■ average output power into 8W 0.5%

■ Output power at 10% THD+N at 1 kHz into 8W 1.5W

■ Shutdown Current 0.6μA

Applications:

■ Portable Computers

■ Desktop Computers

■ Low Voltage Audio Systems
