TPA721 700-mW MONO LOW-VOLTAGE AUDIO POWER AMPLIFIER

The TPA721 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 TPA721 can deliver 250-mW of continuous power into a BTL 8-Ω load at less than 0.6% THD+N throughout voice band freq.
