TPA321 General Description

The TPA321 is a bridge-tied load (BTL) audio power amplifier developed especially for low-voltage applications here internal speakers are required. Operating with a 3.3-V supply, the TPA321 can deliver 250 mW of ontinuous power into a BTL 8- load at less than 1% THD+N throughout voice band frequencies. Although this evice is characterized out to 20 kHz, its operation was optimized for narrower band applications such as cellular ommunications. The BTL configuration eliminates the need for external coupling capacitors on the output in ost applications, which is particularly important for small battery-powered equipment. This device features a hutdown mode for power-sensitive applications with a quiescent current of 0.15 A during shutdown. The PA321 is available in an 8-pin SOIC surface-mount package and the surface-mount PowerPAD™ MSOP, which educes board space by 50% and height by 40%.
