Part Number: OPA2991 Dear TI experts,
My customer drew their own schematic with OPA2991. Could you review this schematic?
++ OPA_VCC+ and OPA_VCC- are 5V~20V variable.
++ DAC0_OUT and DAC1_OUT are 3.3V.
++ the voltage of OPA_OUT+ and OPA_OUT- are related…

Part Number: OPA2991 Hi team,
We are using TI Dual OPA OPA2991IDSGR as Differential input voltage follower configuration.
We want to know what is offset voltage difference between 2 amplifiers, i.e. Voffset_1-Voffset_2. But no information in datasheet…
Part Number: OPA2991 Other Parts Discussed in Thread: OPA4990 , OPA4991 , LMC6032 Hi TIer
My customer is looking forward to AD8643's substitute.
I find OPA2991 is the best pin2pin substitute IC . Is this right? or we have new IC.
But the IBias is 10pA…

My customer is using OPA2991. Below is the schematic they are using.
Customer simulated the Bode plot with different resistor (at the output pin of U3) with…
Part Number: OPA2991 Other Parts Discussed in Thread: TLV9152 Hi team,
What are the main differences between OPA2991 and TLV9152?
Is TLV9152 just a 16V version of OPA2991?
Regards,
Ohashi
Part Number: OPA2991 Other Parts Discussed in Thread: OPA2171 , Hello TI,
I am planning on using the OPA2991S in an upcoming project, and one of the specifications that is most critical for the design is input bias current.
While these devices appear to…
Part Number: OPA2991-Q1 Hi, Please provide the Functional Safety FIT Rate and FMD manual of OPA2991-Q1. Functional Safety Information is required for functional safety FMEDA calculations. Thank you very much!
Part Number: OPA2991 Hello TI,
Do you have any information for the value of the internal pull-down resistor on the SHDN pin on OPA2991S? I intend to use a simple P-Channel Mosfet to disable (pull-up) the SHDN pin(s), but I would like to be confident that…
Part Number: OPA2991 Hi Expert,
my customer has a OPA2991 application, which is power supply is -+15V, input is 0-2.5V, output will be 0-4V(max is 20mA).
customer has concern that there will be large current loading and heat dissipation in the internal…
