The following table shows the input voltages for negative full-scale output, zero output, and positive full-scale
output:

Note that the resistors of the op-amp and the op-amp all introduce gain and offset errors. Those errors can be
trimmed by varying the values of the resistors.
Because of the added offset, the op-amp does not necessarily operate in the best region of its transfer curve
(best linearity around zero) and therefore may introduce unacceptable distortion. For ac signals, an alternative
is described in the following section.
