Full bridge amplifiers are proliferating rapidly in the car audio market, just 5 years ago the idea of full bridge was off-putting but now they make more power in a smaller package with the same relatively low distortion (remember when everyone hated Class D?) However, this generally is only true with high-output power amplifiers (> It is about as basic a design of the circuit as possible. 2. The half bridge is used in some switched-mode power supplies that use synchronous rectifiers and in switching amplifiers. The amplifier features five user selectable gain settings with a gain accuracy of ±0.5% and offers a wide bandwidth to 100kHz. If your amplifier does not claim to be able to bridge, don't try to bridge it.

Hello, I have been looking to use a full bridge strain gauge configuration to make a weighing scale. This is because is a full bridge, as opposed to a half bridge, the output voltage is … Some consider this to be a disadvantage, because more switches typically mean more conduction and switching losses. Be aware of the fact that if your amplifier is a stereo amplifier (amplifying both left and right), bridging it would cause it to become a mono amplifier (amplifying from one; either the left or right). A full-bridge Class D amplifier, however, requires twice as many MOSFET switches as a half-bridge topology.
