BUS SUMMING AMPLIFIER
In addition to its use as a microphone preamplifier, the SSM2019
can be used as a very low noise summing amplifier. Such a circuit
is particularly useful when many medium impedance outputs
are summed together to produce a high effective noise gain.
The principle of the summing amplifier is to ground the SSM2019
inputs. Under these conditions, Pins 1 and 8 are ac virtual grounds
sitting about 0.55 V below ground. To remove the 0.55 V offset,
the circuit of Figure 5 is recommended.
A2 forms a “servo” amplifier feeding the SSM2019 inputs. This
places Pins l and 8 at a true dc virtual ground. R4 in conjunction
with C2 removes the voltage noise of A2, and in fact just about
any operational amplifier will work well here since it is removed
from the signal path. If the dc offset at Pins l and 8 is not too
