Part Number: OPA990 Other Parts Discussed in Thread: TLV9101 , Hi Team, Our customer noticed that the pin assignments and drawings of the OPA990 and TLV9101 SOT-23 6-pin package were not properly matched on the datasheet. They've experienced an issue designing…
Hi Sv,
No problem!
As long as you choose the proper external resistors for your difference amplifier, then I think this would work. Also, why did you choose the OPA170? We have the OPA990, which is our next generation of high voltage op amps that offer…
Hi Tejendra,
OPA990 is the rail to rail op amp, but it is unable to source beyond ±40mA-50mA current range. What are the application's current requirements?
Best,
Raymond
Hi SV,
Lots of great questions:
The maximum current can be changed depending on the type of MOSFET you use and the voltage you apply to the gate.
It's not very obvious but this covered by the Isolation Resistor Stability Video in the Precision Lab…
Part Number: OPA990 Other Parts Discussed in Thread: OPA991 Hi sir,
Please kindly recommend TI P-P solution to replace NCS21911 SOT-5P.
Other spec requirement is:
Offset: 25uV-800uV
VCC: +36V (at least >16V)
Thanks a lot!

Hey Jim
The output close to negative rail gets better with a true rail to rail output device, like the OPA990. The LM321 had to have a unique architecture . Unfortunately we don't have a pin-to-pin option with rail to rail output. The TL343's swing from…
Hi A.M.,
Welcome to E2E! :)
Yes, Clemens is correct. The OPA2990IDR and OPA990IDBVR does not include shutdown feature. We have the OPA990 S IDBVR (SOT-23) for the single channel and the OPA2990 S IDGSR and OPA2990 S IRUGR for the dual channel shutdown options…
Hey Anna,
The product page on ti.com shows that a higher voltage alternative is the OPA990. Please have the customer try with a op that is rated for 30V, like the OPA990.
All the best, Carolina
