APPLICATION INFORMATION
input characteristics
The TL05x and TL05xA are specified with a minimum and a maximum input voltage that, if exceeded at either
input, could cause the device to malfunction.
Because of the extremely high input impedance and resulting low-bias current requirements, the TL05x and
TL05xA are well suited for low-level signal processing; however, leakage currents on printed-circuit boards and
sockets easily can exceed bias current requirements and cause degradation in system performance. It is good
practice to include guard rings around inputs (see Figure 83). These guards should be driven from a
low-impedance source at the same voltage level as the common-mode input.
Unused amplifiers should be connected as grounded unity-gain followers to avoid possible oscillation.

noise performance
The noise specifications in operational amplifier circuits are greatly dependent on the current in the first-stage
differential amplifier. The low input-bias current requirements of the TL05x and TL05xA result in a very low
current noise. This feature makes the devices especially favorable over bipolar devices when using values of
circuit impedance greater than 50 k
