As is shown above, using the double power supply TL062 op-amp, electrical testing found TL062 VEE is pulled down to 2 v, is what circumstance? Whether the circuit design problem?

Known 10 ohm resistor, 5 v, 5 v power supply are normal, flow ability both in amp levels (mature circuit, has been used many times),

Today the first time that the voltage is not normal for TL062 also is such, is what circumstance? Consult,

CodePudding user response:

VCC is how many v? + 2 v?
It can't be that big current (300 ma), has a short circuit PCB?
