Part Number: THS4021 Tool/software: Hi
This is probably a daft question but Ive picked up a old design which I have been tasked to fix. The previous designer has powered the THS4021 amplifier using a dual supply of +22 and -5V, I believe they have done…
Part Number: THS4021 we have MPN:THS4021CDGNG4 in our database. But it is recognizable at website. Does its MPN 2format is change or it lifecycle status is obsolete?
Part Number: THS4021 Hi Sir,
The application is that we want to detect the ripples of the DC bias such as 24V etc in the 1.8GHz products.
can comparator be use in this application? We are trying to detect the ripples on top of a DC voltage. Could…
Part Number: THS4021 Hi
We have received notification that the THS4021CDGNR specification will change.
PCN Notice_TI.pdf
The reason is accurately reflect device characteristics.
What I would like to confirm is, was the spec changed this time the…

Hi team,
I got a question from customer.
Using the THS4021 op amp chip, no matter how it is connected, it will self oscillate.
The circuit board is as follows:
No matter whether the single power supply or dual power…
Hello Shi,
Not sure why the transient analysis still isn't running for you. Unfortunately I am not able to debug your file on LTSpice due to legal constraints.
It is worth noting, however, that the THS4021 isn't a unity gain device. Using it in a…
Hello,
Why have you chosen the THS4021 for this application? This is a decompensated amplifier and isn't designed to be used below a gain of 10 (or -9) without proper compensation.
Best,
Hasan Babiker
Part Number: THS4021 Other Parts Discussed in Thread: OPA838 , THS4631 , OPA2810 Hello,
I'm considering using the THS4021 as an amplifier in a discrete instrumentation arrangement. I'll need to consider nulling the previous amplifier stage errors as…
Part Number: THS4021 Dear Expert,
I have a question about THS4021.

Please tell me about the noise characteristics of THS 4021.
A graph of noise appears on the first page of the data sheet…
Part Number: THS4021
Problem:
THS4021 is used in both inverting and non-inverting configuration. In non-inverting configuration, when the gain of opamp is such that the output is less than +/-15V, there are many ripples or noise when the pulse waveform…
