TPA0233DGQG4 Datasheet PDF - TI

●description

●The TPA0233 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-Ω impedance. The mono signal is created by summing left and right inputs. The amplifier can be reconfigured on the fly to drive two stereo single-ended (SE) signals into head phones. This makes the device ideal for use in small notebook computers, PDAs, digital personal audio players, anyplace a mono speaker and stereo headphones are required. From a 5-V supply, the TPA0233 deliver 2 W of power into a 4-Ω speaker.
