5.1.2 Input Characteristics

The TL05x and TL05xA are specified with a minimum and a maximum input voltage that, if exceeded at either input, can 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. Good practice is to include guard rings around inputs (see Figure 5-3). These guards can be driven from a low-impedance source at the same voltage level as the common-mode input.

Unused amplifiers can be connected as grounded unity-gain followers to avoid possible oscillation.
