The TLE202x-Q1 series offers external null pins that further reduce the input offset voltage. Figure 6-2 shows how to connect the circuit if this feature is desired. Adjust the external resistance value to achieve desired performance. When external null is not needed, leave the null pins disconnected. Only use this adjustment to null the offset of the operational amplifier. Do not use this adjustment to compensate for offsets created elsewhere in a system because of the possible introduction of additional temperature drift.

Internal resistances vary; unexpected results are sometimes produced when using fixed resistors to null the offset of the amplifier.
