Output offset voltage is the error introduced in the output voltage due to the inherent input offset voltage VOS, of

an amplifier.

Output Offset Voltage = (Input Offset Voltage) (Gain)

In the above configuration, the resistors R5 and R6 determine the nominal voltage around which the input signal,

VIN should be symmetrical. The high frequency component of the input signal VIN will be unaffected while the low

frequency component will be nulled since the DC level of the output will be the input offset voltage of the

LMC6462 plus the bias voltage. This implies that the output offset voltage due to the top amplifier will be

eliminated.
