Part Number: OPA134 Tool/software: As you mentioned earlier, the open-loop output impedance change might affect stability but both datasheet (SBOS058A and SBOS058B) show 10Ω at 10kHz, also their capacitive load graphs (Rev A Fig. 26 vs. Rev B Figs. 5…
Part Number: OPA134 Tool/software: Hello TI Team,
We are currently reviewing PCN 20240902002.1 related to the OPA134 datasheet revision (from SBOS058 A to SBOS058 B ), issued in September 2024. Find attached PDF for PCN.
To assess the potential…
Part Number: OPA134 Tool/software: The TRIM function of OPA134 has disappeared in Rev.B and it seems to have become NC.
(Example: 8-pin SOIC 1pin and 8pin)
I have a few questions, so please answer them.
1. When did the TRIM function disappear? …
Part Number: OPA134 Dear technical support Team,
In the recent PCN for OPA134, I noticed that pins 1 and 8 have been changed to NC, with the explanation that external trimming is no longer required due to laser trimming.
However, the Rev.A datasheet…
Part Number: OPA134 Tool/software: Hello. - Hello. I am asking about REVISION. I am having a problem with REV B, because the offset adjustment terminal is N.C, I am having a problem with a mounting board that requires voltage adjustment using the offset…
Part Number: OPA134 Tool/software: Hi team,
PCN# 20240902002.1 is only a change in the datasheet, but it is a change in the electrical specifications. Is this only a change to the datasheet? If it is only a change in the data sheet, does it mean that…
Part Number: OPA134 Hello,
I'm experiencing vibration problems with an amplifier stage consisting of the OPA134UA operational amplifier.
In the 31-33 Hz frequency band, it oscillates and disturbs my measurement signal.
Have you seen this problem…
Part Number: OPA134 Tool/software: Hello, I'm reading a preceding thread [OPA134: About pcn] e2e.ti.com/.../opa134-about-pcn
We would ask some more explanation to understand the removal of the Trim feature.
- Is it harmful if the existing circuit…
Hallo,
I am building a very simple low pass subwoofer filter cutting of on approx 40Hz.
Why is a square wave not going trough the filter stages as a sqare?
After the Buffer the 0,360 mV 30Hz sqarewave stays in shape.
If I have a Audio bass impuls…
Part Number: OPA134 Hi Dear,
As shown in the following figure, without changing the drift of the operational amplifier, the offset can be zeroed in the circuit. Does TI have such a mature design, and how to choose A1 and A2 operational amplifiers?
