Part Number: OPA397 Hello TI,
Just FYI, there is an error in the OPA397 datasheet. Figure 6.8 is labeled as "Input Bias Current vs. Temperature", but the graph is of "Input Bias Current vs. Common-Mode Voltage" at Vs=5.5V
Have a…
Hi Albert,
Ah yes of course- the OPA397 is not yet auto-qualed., but the higher-performance version will be next year called OPA392.
The best device at the moment then is probably OPA376-Q1, or OPA388-Q1 for ultra-low offset chopper amp.

Hi Marek Lis,
Thanks for the info and recommendation on opamp. Now we have better understanding with parameter selection of opamp. Apart from "Input bias" and "Offset Voltage", do we need to consider anything else? Unfortunately OPA392 and OPA397 are…

I have two question want to ask.
Can the op amp be used as a comparator? Can the tlv4333 op amp be used as a Hysteresis comparator…

My customer is using TLV2333.
The input differential voltage is 2V, but the graph below is expressed only up to 800mV. I want to know the input…
Part Number: OPA191 Other Parts Discussed in Thread: ADS1015 , OPA197 , OPA397 , OPA350 , OPA333 Hi,
I am looking for the headroom voltage value of OPA191. How can I find this value in the datasheet? Is it possible to find it out?
Thank you.
One more comment to those who may come across this thread. What I initially failed to notice was that, according to docs, OPA392 maintains low I B (-20/+30fA) within V CM =±1.5V range (is it relative to V S /2 ?) and above V CM =1V I B+ goes through the roof…
Part Number: OPA325 Other Parts Discussed in Thread: OPA397 , Hi there,
sometimes datasheets report several values for a single parameter acquired using different test conditions, e.g., the parameter is measured using different temperature ranges.
One expects…
