Hi SV,
This ended up taking longer than I intended. For the stability analysis, I had to split the supply rails. I also had to go in and increase the supplies to help the circuit converge.
As you can see here, the phase margin is 32.65 degrees…
Hello James,
SGM8210 comes in difrerent channel count and packages. So I don't know which one is desired.
I recommend, OPA990, OPA2990, and OPA4990 as replacement devices.
Part Number: TLV9062 Other Parts Discussed in Thread: TLV9302 , OPA2990 , TLV9042 , TLV9352 , TLV9052 , TLV9152 , OPA2991 , TLV9102 , LM358B , TLV9002 Hello,
I was reviewing this E2E post which states that any of these operational amplifiers could also…
Hi Chuanxiao,
Something else you might want to take a look at is our new part, the OPA2990. This new part has an interesting input protection scheme, shown on page 24. It should satisfy your current needs while also having a faster slew rate and better…
Part Number: OPA2171-EP Other Parts Discussed in Thread: OPA2170 , , OPA2171 , OPA2990 , TLV9302 Hi All,
We are trying to find a P2P solution for OPA2170, and we notice that OPA2171-EP is an option. I would like to know the main difference between OPA2171…
Part Number: OPA4990 Other Parts Discussed in Thread: DAC70502 Hi team,
Currently I want to provide a discrete solution for customers which use DAC70502+OPA2990S/4990S to output both V/I on the same board.
Our AE recommend this circuit for me as below…
Hi Wayne,
Not all specifications are specified with a supply voltage at 2.7V. For example, Aol, PSRR, and CMRR all have test conditions using at least a 4V supply.
If the customer requires a high voltage device specified down to 2.7V I recommend taking…
Hi Sathish,
Kai is correct, the OPA171 has internal back to back diodes. When a differential voltage is applied to the device one of the diodes will turn on, clamping the differential voltage. Please see " Op Amps used as Comparators - is it okay? …
