TPA731 - 700-mW Mono Low-Voltage Audio Power Amplifier
The TPA731 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 TPA731 can deliver 250-mW of continuous power into a BTL 8-Ω load at less than 0.6% THD+N throughout voice band freq
