PRODUCTION DATA
The TLE206x, TLE206xA, and TLE206xB are specified with a minimum and a maximum input voltage that, if exceeded at either input, can cause the device to malfunction. Due to the extremely high input impedance and resulting low bias current requirements, the TLE206x, TLE206xA, and TLE206xB are designed for low-level signal processing. However, leakage currents on printed circuit boards and sockets can easily exceed bias current requirements and cause degradation in system performance. It is good practice to include guard rings around inputs (see Figure 7-1). Drive these guards from a low-impedance source at the same voltage level as the common-mode input
