So...what happens when you violate the Vdig rules...does it by, any chance, burn the chip badly?
View ArticleForum Post: RE: OPA564 digital flags....
Exceeding the maximum voltage on OPA564 Vdig of (V-)+5.5V, even momentarily, by more than few hundred millivolts may permanently damage the IC. Thus, if this is possible to occur, you must use an...

Is it possible we can talk over email or phone? We are having huge issues with this chip. I am not sure if it is the board design, the circuit design, or just the chip itself. Thanks

@Pete Semig: As I had said earlier, R1-R4 can vary user can give them any value. Actually this circuit is used for finding unknown resistance. All I have to do is when bridge is unbalanced by 0.1uV i.e...

For the TLV3202AIDGK,What is the maximum Iq at the negative input at the following situations: 1 : Vcc = 5V Positive input = 2.5V Negative input = 0.5V 2: Vcc = 5V Positive input = 2.5V Negative input...

This power supply condition is valid for the INA128 because the total voltage across the INA128 is 36V (the absolute maximum rating of the part). However, if there is any variation in the power supply...

Although this is not TI's device, the answer is fairly simple. At low frequency the capacitor can be considered an open circuit. So the gain of the circuit is 20*100k/100k = 20. At high frequency, the...

Hi Komal, For debugging purposes, try removing the external current limiting BJT (Q2) and replacing resistor R3 with 0 ohms and do a basic measurement of the output current vs. input voltage. I would...

I have never found a really good explanation of the servo loop for opamp characterization tests. I presume the servo amplifier is there to ensure the output of the DUT is unloaded because the reality...

Atsushi, The problem with your circuit is that you incorrectly connected the feedback in the first op amp - it must be connected from the non-inverting input terminal since the second op amp already...
