Balance input in bridge configuration
A helpful characteristic of the TDA7360 is that, in bridge configuration, a signal present on
both the input capacitors is amplified by the same amount and it is present in phase at the
outputs, so this signal does not produce effects on the load.The typical value of CMRR is
46dB.
Looking at
to the ground of the hypothetical preamplifier is amplified of a factor equal to the gain of the
amplifier (2 · Gv). Using a configuration of
output multiplied by the factor 2 · Gv/200.
This means less distortion, less noise (e.g. motor cassette noise) and/or a simplification of
the layout of PC board.
The only limitation of this balanced input is the maximum amplitude of common mode
signals (few tens of millivolt) to avoid a loss of output power due to the common mode signal
on the output, but in a large number of cases this signal is within this range.
