One of my customers is evaluating OPA192 for their new products.
At this moment, they have the following questions.
Could you please give me your reply for them?
Q1. We can see a ESD diode is placed between IN- and VDD terminal in Figure 65 on page 29 of OPA192 datasheet (Ver SBOS620E).
How much is the allowable DC current value of the ESD diode? Is it 10mA?
Q2. If IN- input current is less than 10mA as Absolute maximum ratings table, Is the diode not damaged even if IN- voltage is higher than VDD voltage + 0.5V?
Q3. Can IN- terminal be applied a voltage less than 0.5V when VDD voltage is 0V?
Your reply would be much appreciated.
