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 will…
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?
Part Number: OPA134 Hi there,
I have an older high performance DAC and I'm looking to replace some of the older capacitors on the circuit board.
I'm a amateur electronics kit builder so I don't have knowledge of circuit design.
If you look…
Part Number: OPA134 I have a opa134 soldered into a simple non-inverting opamp circuit shown below.
Input is 1Vp-p. The output is severely distorted unless the supply rails are increased to +/-15V. The datasheet says it can take +/-2.5V minimum. What…
Part Number: OPA627 Other Parts Discussed in Thread: OPA134 , TPA6120A2 , OPA828 Hello, I would like to use the OPA627 and the OPA134 in optimal wiring (non inverting) in front of a TPA6120A2.
Unfortunately, despite an intensive search, I did not find any…
Hello all,
The OPA134 data sheet RC in Fig. 30 is aiming at about 3dB peaking - some discussion and an updated set of RC values for a 30kHz Butterworth are in the attached file. The first key thing is what the model is saying for GBP. The freshly updated…
Hey Mochi,
Yes, the 2ch NE5532A is being updated to the 300mm wafer like the PCN doc mentions but the 1ch NE5534AD/ADR/AP is going to EOL on the Last date to order mentioned in the PDN doc. And yes, the recommended replacements are the OPA1677 and OPA134…
