input bias and offset current
At the picoampere bias current level typical of the TLE207x and TLE207xA, accurate measurement of the bias
current becomes difficult. Not only does this measurement require a picoammeter but test socket leakages can
easily exceed the actual device bias currents. To accurately measure these small currents, Texas Instruments
uses a two-step process. The socket leakage is measured using picoammeters with bias voltages applied but
with no device in the socket. The device is then inserted in the socket and a second test is performed that
measures both the socket leakage and the device input bias current. The two measurements are then
subtracted algebraically to determine the bias current of the device.
