General Description
The LPA4990 is an audio power amplifier designed for portable communication device applications such as GPS trackers. The LPA4990 is capable of delivering 1.2W of continuous average power to an 8? load from a 5.2V power supply with less than 1% distortion (THD+N).
The LPA4990 is designed specifically to provide high quality output audio power with a minimal number of external components. The LPA4990 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited where minimal board or solution size is a primary requirement. It features a low-power shutdown mode, which is achieved by driving the /SHDNpin with logic low. Additionally, the LPA4990 features an internal thermal shutdown protection.
The LPA4990 contains circuitry to prevent “pop and click” noise that would occur during turn-on and turn-off transitions. For maximum flexibility, the LPA4990 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on and turn-off times (with the bypass capacitor). The LPA4990 is available in a MSOP-8 package.
