APPLICATION INFORMATION
input characteristics
The TL03x and TL03xA are specified with a minimum and a maximum input voltage that, if exceeded at either
input, could cause the device to malfunction.
Due to of the extremely high input impedance and resulting low bias-current requirements, the TL03x and
TL03xA 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 a good
practice to include guard rings around inputs (see Figure 61). These guard rings 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 oscillation.
