Part Number: OPA2890 Other Parts Discussed in Thread: OPA890 , THS3491 , LMH6703 Tool/software: Dear Technical Support Team,
What is the maximum frequency of the OPA890 for square wave?
10MHz seems to operate correctly, however 250MHz (500Mhz) is required…
Part Number: OPA2890 Other Parts Discussed in Thread: BUF634
I Designed with this circuit by TI Filter design, with OPA 2890.
The 4.2 kHz filtering circuit ran as intended.
But when I only change the center frequency 4.2 to 5.5 kHz,
It has…
Part Number: OPA2890 Dear Sir/Madam,
I am after some PCB routing advice on connecting one OPA2890 (gain of 2) to four OPA2890 (gain of 1). The delay between the OPA2890 is not important just signal quality.
Regards Joe
Part Number: OPA2890 Hi, I am working for SARADC single input for ATE testing with multiple DUT (with multiple ADC input in one DUT as picture). I am seeking help if the circuit i draw is doable and any recommendation appreciated.
SARADC with 20kHz max…

Dear Technical Support Team,
I have simulation issue with Pspice for TI. I'm trying to simulate non-inverting amp with adding 1V offset to negative input pin(-), however it doesn…
Part Number: OPA2890 Before I leave this newer (to me) BP filter topology, I stepped through a more demanding design targeting total 6dB gain with 1MHz center and only 50kHz BW forcing a 4th order solution in Filterpro. It does not support this topology…
Hello Antonio,
I also tried swapping the OPA2690 and OPA2890 onto the TSC file you shared; the OPA2890 has similar offset while the OPA2690 has worse offset. Between three parts, the OPA2690 has double or more input bias current.
I think the high resistor…
And I was actually thinking of the OPA2890 - these are both very lower power devices - I tend not to use the OPA2690 unless that high slew rate is required.
You might also consider the OPA2625
So you are doing a buffer?
A 10MHz 2Vpp sinusoid requires a peak dV/dT of 62.8V/usec.
If you can use a 5V part, use the OPA2837 - if you need a 10V total supply, use the OPA2890
