Part Number: THS4131 Other Parts Discussed in Thread: OPA131 Hi All,
I am using the THS4131. The fully differential amplifier does not seem to be giving a balanced output. I find there is a 50mV difference from the common mode signal level.
In the…
Richie,
Thank you for this thorough description of you applicaiton needs. For your application issue I would recommend that you use a Bessel, Bandpass filter that uses the Sallen-Key topology. This filter would look like.
The center frequency for…
HI Shadyn,
We have a few options of modern JFET input amplifiers offering better performance and precision than the legacy OPA111SM; however, these are not available on the PDIP or TO-CAN packages. The OPA627SM is a 45-MHz previous generation JFET amplifier…
Hi Robert,
I think I had pulled the OPA131 model from the product web page and that is how the association with the OPA121 model came about. It looks like you overcame that issue.
The problem with your circuit was the power supplies were not transferred…
Hi Qi,
Okay, here are some answers / comments to your previous post:
The OPA131 does have excellent capacitive load drive compared to similar amplifiers. Maintaining stability above a few 100pF is usually not possible with precision small-signal op…
Karthik,
Any op amp in the TO-99 metal package will be quite expensive.
The OPA129 is much lower cost but uses the same IC internally. It is in an SO-8 package but has a non-standard pinout.
The OPA131 is a lower cost op amp with similar behavior…
