description

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-Ω 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.
