input bias and offset current
At the picoampere bias current level typical of the TLE206x, TLE2064xA, and TLE206xB, 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 into the socket and a
second test that measures both the socket leakage and the device input bias current is performed. The two
measurements are then subtracted algebraically to determine the bias current of the device.
