Part Number: OPA891 Other Parts Discussed in Thread: OPA892 , , OPA2892 Hello Experts,
This board will be used for designing a probe for measuring switching currents of a high-speed SOC.
The input voltage range is expected as 250uV to 7.5mV.
OPA891 and…
Part Number: OPA891 Tool/software: The spec sheet says the Input Z in the differential mode is 6K.
I downloaded the TINA simulation example which in a non inverting buffer, (gain of 1) and inserted a 100k resistor in series with the plus input. Sure…
Part Number: OPA891 The OPA891 data sheet front-page "Applications" section cites "Professional Audio Amplifier" but the minimum recommended build-out resistance is 20R.
I assume the "Pro Amplifier" refers to a headphone amplifier…
Part Number: OPA891 Hi TI how is the THD and IMD graphs measured in the OPA891 datasheet? Figure 5-35 shows THD+n below -135dB and figure 5-36 IMD in the ballpart. i dont know any THD analyzer that can measure this low THD...

Hello Sean,
I do recommend working with the OPA891 and OPA810. The OPA891 is a part of our family of high-voltage, low noise op-amps.
We also have the OPA2891 if you require a dual-channel amplifier. Thank you for trying and testing the method I recommended…
Part Number: LMH6611 Other Parts Discussed in Thread: THS3491 , OPA2675 , OPA891 Tool/software: Hi team,
Do we have higher current amplifier but with similar spec with LMH6611 ? LMH6611's 100mA drive current is not enough.
Hello,
EMI is a complex topic. Proper shielding can help. You can see some comparisons in the app brief below. Quoting from the app brief, "Over the past 7 years, Texas Instruments has taken the initiative to include EMI/RF filters in all the op amps…
Hello Sarath,
My initial recommendation would be to check out our new OPA891. The device meets your slew rate and output current needs, as well as having a high GBWP and higher supply rails.
If you have additional spec concerns or needs, I can provide…
Part Number: THS4131 Other Parts Discussed in Thread: OPA891 , OPA365 , THS4531A , THS4521 , OPA836 Tool/software: Presently I have a system working fine, except it is picking some noise from a neighboring system.
The noise is picked up by the ribbon…
