APPLICATION INFORMATION
input offset voltage nulling
The TLE2141 series offers external null pins that can be used to further reduce the input offset voltage. If this
feature is desired, connect the circuit of Figure 35 as shown. If external nulling is not needed, the null pins may
be left unconnected.
