Either input may be grounded, with bi-directional drive provided to the other. It is also possible to connect one
input to a positive reference, with the input signal varying about this voltage. If the reference voltage is above 5V,
R₂ and R₃ are not required.
HIGH VOLTAGE AMPLIFIERS
The voltage swing delivered to the load can be doubled by using the bridge connection shown here. Output
clamping to the supplies can be provided by using a bridge-rectifier assembly.
One limitation of the standard bridge connection is that the load cannot be returned to ground. This can be
circumvented by operating the bridge with floating supplies, as shown above. For single-ended drive, either input
can be grounded.
This circuit shows how two amplifiers can be cascaded to double output swing. The advantage over the bridge is
that the output can be increased with any number of stages, although separate supplies are required for each.
