TPA0233 Datasheet (Texas Instruments) - 2-W Mono Audio Power Amplifier

TPA0233, 2-W Mono Audio Power Amplifier

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.
