Nuts and Volts - October 2015

reading with a 10 mV drop, which is a 10X lower measurement burden relative to the original circuit.

If you add the input diode protection resistor back in, then you incur only 0.7 mV max uncompensated offset because of the TLE2021’s enhanced performance. If you do this, then there’s really no reason to keep those diodes — you can rely on the op-amp’s input pin protection circuit.
