Description
The TDA7297 is a dual bridge amplifier specially designed for TV and Portable Radio applications.
A bridge amplifier is an electronic amplifier that is designed to measure small signals in the presence of a large common-mode voltage. It is commonly used in measuring applications where the signal of interest is small and needs to be amplified while rejecting the common-mode voltage that can be present due to noise or other sources.
The bridge amplifier is used to amplify this signal while rejecting the common-mode voltage that is present across all four arms of the bridge.
