Product Summary
The TPA0253DGQ is a 1W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 8-Ω impedance. The mono signal is created by summing left and right inputs internally. The TPA0253DGQ can be reconfigured on the fly to drive two stereo single-ended (SE) signals into headphones. This makes the TPA0253DGQ ideal for use in small notebook computers, PDAs, digital personal audio players, anyplace a mono speaker and stereo headphones are required. From a 5V supply, the TPA0253DGQ can deliver 1-W of power into an 8Ω speaker.
