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 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 Other Parts Discussed in Thread: TINA-TI , OPA2991
I follow TI Designs – Precision: Verified Design 1 MHz, Single-Supply, Photodiode Amplifier Reference Design to design my TIA circuit with OPA991.
For the enough I/V gain, Rfb…
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 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,
Shinichi
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…
Part Number: OPA991 Other Parts Discussed in Thread: TLV9301 Hello ,
i'm not sure if I can use OPA991 and TLV9301 with single supply configuration. Because in some Datasheets it is said explicit, that those Amplifiers can be used with single Supply.…
Part Number: OPA991-Q1 Other Parts Discussed in Thread: OPA991 , TINA-TI hi experts
i saw the Input voltage range spec in our datasheet--MIN input voltage is (V-)-0.1V. if OPA991 is used in Single-Supply situation, such as (V-) is 0V, GND.
in this situation…
Part Number: OPA991 Other Parts Discussed in Thread: OPA2991 , OPA341 TI-TINA SPICE Model for OPA991 uses the dual Opamp OPA2991 model. However, the OPA991 has a shutdown pin function that is not present in the OPA2991. How does one simulate the shutdown…
