11. output phase reversal Many FET input op amps such as TL061 types exhibit phase reversal of the output when the input common mode range is exceeded This can occur in voltage follower circuits causing serious problems in control loop applications Input terminals are diode clamped to the power supply rails for ESD protection If the input voltage can exceed the negative supply by 500mV input current should be limited to 2mA or less If the input current is not adequately limited you may see unpredicatable behavior in the other amplifiers in the package This is easily accomplished with an input resistor as shown in Figure 1 Many input signals are inherently current limited therefore a limiting resistor may not be required lovERLOAD Inputs are internally clamped to V and V FIGURE 1 Input Current Protection for Voltages Exceed ing the Supply Voltage HIGH SIDE CURRENT SENSING Many applications require the sensing of signals near the positive supply The common mode input range of OPA137 op amps includes the positive rail enabling them to be used to sense power supply currents as shown in Figure 2 Zetex Darlington ZTX712 Ground referred output FIGURE 2 High Side Current Monitor INPUT BIAS CURRENT The input bias current is approximately 5pA at room tem perature and increases with temperature as shown in the typical performance curve Input Bias Current vs Tempera ture Input Bia
