input bias and offset current
At the picoampere bias-current level typical of the TLE208x and TLE208xA, accurate measurement of the bias
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.
