Description for the TPA0213EVM
The TPA0213 is a 2-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 4 Ohm 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 use in small notebook computers, PDAs, Digital Personal Audio players - anyplace a mono speaker and stereo head phones are required.
