Hi Team
I simulated the following circuit and found VF1 has output but Vout doesn't have output. Can you help show your comment why this happen?
Part Number: OPA991-Q1 Other Parts Discussed in Thread: OPA991 , TINA-TI , OPA323 Tool/software: Hello Analog Experts,
I am new to amplifier circuits and have a question regarding high-speed signal distortion with the OPA991.
Given the OPA991’s gain-bandwidth…
Part Number: OPA991-Q1 Hello TI,
I am using OPA991-Q1 to supply few logic devices. I could see in the datasheet the maximum current that this opamp can supply is +/-75mA. Is this short ciruit current ? can you share me the maximum or nominal allowable…

Part Number: OPA991 Hi -
Customer is reporting an issue where they are powering the op-amp before their signal gets to the input of the op amp. Not sure the state it is in prior to signal present, might be floating? I don't have schematic and I'm also…
Part Number: OPA991-Q1 Other Parts Discussed in Thread: OPA991 Hello ,
I have build an high side differential amplifier using OPA991.
In this schematic i have used an offset about 2.5V.
My expectation was that if the current is 12A (1 Ohm load at 12V…
Part Number: OPA991 Hi team,
I got a customer who has the below question; your help is greatly appreciated!
"Can you tell me the difference between two op-amp part numbers? OPA991IDCKR and OPA991TIDCKR. Data suggests they are identical but it doesn…
Part Number: OPA991 Hi,
We are using OPA991 for rail-to-rail output of -12V to +12V. In addition to it, we are adding a divider resistor circuit to make the -ve measurement to +ve for the controller ADC.
The PWM pulse with 1KHz is fed into the op-amp…
Part Number: OPA991-Q1 Dear Specialists,
My customer is interested in OPA991SQDBVRQ1.
Could you please let us know when is the RTM?
I appreciate your great help in advance.
Best regards,

Hey Michael,
Good to hear the TLV9361 is a good fit for the application. Thank you for sharing
The TLV is a similar design to the OPA version with a lower cost and reduced performance, here is a comparison table.
As you can see in this scenario, the…
