TPA0233DGQG4 Description
The TPA0233DGQG4 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. Each device is offered in a compact MSOP-PowerPad-10 package, and an extended industrial temperature range from –40°C to 125°C makes these devices suitable in a wide variety of commercial and industrial applications.
