Part Number: OPA4991 The FA test request feedback, the IV test, only test Pin1 vs All pin and Pin1 Vs GND. Is it right?
We need all pin IV test, and the failed pin may be not the Pin1.

Hi,
I'm using this circuit as an overvoltage protection circuit. I've tested it, and it works. However, there's an issue: when a load is connected, the gate voltage drops to around 3V(still Mosfet is on ). When…
Part Number: OPA4991-Q1 Is it possible to send me numerical data for performance curve, I(B+), I(B-), I(os) versus temperature? It's figure 6-13 in the data sheet. I am developing a worst case database for the part for Blue Origin.
Part Number: OPA4991-Q1 Hi, my name is Jeffrey Lee. I working for Blue Origin developing a worst case database for the OPA4991Q. Is it possible to provide information on the post burn-in deltas for parameters such as Vios, Ib, Ios, A(ol) and I(supply…

We should get the curve form of OPA4991's operation frequency and power consumption. could you help on the case?
Part Number: OPA4991-Q1 Hello,
Can you please clarify which row to look at in the datasheet? I see 4 rows. Since I am using the Q1 version, I can narrow it down to two rows but now I'm confused on which maximum Iq value I should use in my power calcs…
Part Number: OPA4991 Tool/software: Hi Sir :
We are using OPA4991 instrument amplifier for small signal amplification, but we are currently facing a problem. The differential input itself introduces a signal of about 6mv, which has a significant impact…
Part Number: OPA4991-Q1 Tool/software: The datasheet for OPAx991-Q1 lists the short circuit current (Isc) as ±75mA. Does anyone know if running up to that current will degrade or damage the IC? And a step further, Can the device run long term at anything…
