Description
AI
The TPA751 is a bridge-tied load (BTL) audio power amplifier developed especially for low-voltage applications where internal speakers are required. Operating with a 3.3-V supply, the TPA751 can deliver 250-mW of continuous power into a BTL 8-load at less than 0.6% THD+N throughout voice band frequencies. Although this device is characterized out to 20 kHz, its operation is optimized for narrower band applications such as wireless communications. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications, which is particularly important for small battery-powered equipment. This device features a shutdown mode for power-sensitive applications with a supply current of 1.5 nA during shutdown. The TPA751 is available in a 3.0 × 3.0 mm MicroStar Junior™ (BGA), 8-pin SOIC surface-mount package and a surface-mount PowerPAD™ MSOP.
