TPA0253 - 1-W MONO AUDIO POWER AMPLIFIER
The TPA0253 is a 1-W 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 amplifier can be reconfigured on the fly to drive two stereo single-ended (SE) signals into headphones.
