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…
Part Number: OPA4990 Other Parts Discussed in Thread: OPA4991 Hi team,
Does OPA4990 or OPA4991 support Non-inverting output with Gain = 1? I'm asking this because there are no description about stability of unity gain in the datasheet.
From PSpice…
Part Number: OPA4990 1. Is the short-circuit current of +/- 80mA for 4 channels or each channel?
2. When the load increase, this current will decrease, right?
3. How will the open-loop output impedance affect on the max load current?
4. Does the X2QFN…
Part Number: OPA4990 Other Parts Discussed in Thread: OPA4197 , OPA2990 Hello Does OPA4990 have POR? My customer wants to use an OpAmp that doesn't have POR to avoid inrush current at POR release timing.
Regards, Oba
Part Number: OPA4990 Other Parts Discussed in Thread: LM2902KAV , OPA4171 , , TLV9154 Hi Support team
my customer would like to optimize the performance of Op-Amp for low-side current sense. (LM2902KAV, OPA4990, OPA4171.)
The Op-Amp Circuit is as below…
Part Number: OPA4990 Hi Support team
since the noise coupling, my customer would like to increase the output cap to maybe 0.1uF to filter the noise,
the AC_L1 & AC_N1 is 50-60HZ AC sin wave AC input
the application is as following, pls kindly let…
Part Number: OPA4990 Other Parts Discussed in Thread: OPA2990 Hi Team,
I have two questions.
[Q1]
Could you please let us know RTM of OPA4990IPWR(TSSOP) and OPA4990IRUCR(QFN)?
[Q2]
Do you have plan of development of VSSOP PKG?
If yes, could you please…
Part Number: OPA4990 Other Parts Discussed in Thread: TLV9304 , , OPA4991 , OPA2991 , TLV9352 , TLV9354 Hi sirs,
Please kindly suggest if we have p-p solution to replace MC33174DT.
Vin 40V, 4Ch.
Thanks a lot!

1.83 V × 9 = 16.47 V. But the LM224A does not have rail-to-rail outputs; the V OH specification shows that even a small output current requires a headroom of 1.5 V to the positive supply.
You could change the amplification factor so that the output…
