Table 2. Optolinear amplifiers
These amplifiers provide either an inverting or non-
inverting transfer gain based upon the type of input
and output amplifier. Table 2 shows the various con-
figurations along with the specific transfer gain equa-
tions. The offset column refers to the calculation of the
output offset or V

age output for a zero voltage input. The non-inverting
input amplifier requires the use of a bipolar supply,
while the inverting input stage can be implemented
with single supply operational amplifiers that permit
operation close to ground.
