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: 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…
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…
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…
Part Number: OPA134 Other Parts Discussed in Thread: LM386 , , ULN2004A , ULN2002A , ULN2003A , LM4871 I am creating a device that vibrates the 6 strings of a guitar. Let me explain what I have working, then let me explain why I need something better. From…
Also Tengfei,
This article came up yesterday in a different discussion, explains this in more detail with a step by step example using the OPA134 as an example device,

Dear,
Now, I´m designing alarm tone generator with microcontroller. Microcontroller generate square signal output at 1450Hz. This output have a voltge divider and low pass filter for volume control and attenuation at frequencies outside…
Part Number: OPA134 Other Parts Discussed in Thread: DRV135 , ISO7710 , TINA-TI Hi,
In the last post "OPA134: Useful opam'p for audio tone from microcontroller", was unfinished and now I attach a new and improved design with Single-Channel Digital Isolator…
Part Number: PCM1792A Other Parts Discussed in Thread: PCM1792 , OPA134 , , OPA1612 Figure 37 in the datasheet for the PCM1792 shows a typical OP-AMP setup to first convert the current output of the DAC to a voltage (U1 and U2) and then to add the two differential…
