TPA0223 Overview
The TPA0223 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4-Ω impedance. 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 small notebook puters, PDAs, digital personal audio players, anyplace a mono speaker and stereo headphones are required.
