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.
