Typical Single-Supply Applications

where
t is the time the amplifier input takes to move from
1.67V to 3.33V. The calculations are shown below.
where
τ
= RC = 0.68 seconds
→
t

= 0.27 seconds.
and

= 0.75 seconds
Then,

LOW FREQUENCY NULL
Output offset voltage is the error introduced in the output
voltage due to the inherent input offset voltage V
OS
, of an
amplifier.
Output Offset Voltage = (Input Offset Voltage) (Gain)
In the above configuration, the resistors R
and R
deter-
mine the nominal voltage around which the input signal, V
IN
should be symmetrical. The high frequency component of
the input signal V
will be unaffected while the low fre-
quency 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.
