The TPA311 is a bridge-loaded (BTL) or single-ended (SE) audio power amplifier developed for low voltage applications in internal and external speaker headphone operation, especially when required. Powered from a 3.3-V power supply, it is capable of delivering 8 250 MW of continuous output power under the TPA311 line -Less than 1% THD+N loads the entire speech audio band. Although this device is characterized by a range of up to 20 kHz, its operation is optimized for narrow band applications such as mobile communications. The BTL configuration eliminates the output to most applications on an external coupling capacitor, which is an important requirement especially for small battery-powered devices. A TPA311 is unique in that it allows switching of BTL amplifiersofseleniumRightA headset driver is required.
