Other Parts Discussed in Thread: OPA1604 I had an OPA1604 fail in a catastrophic way. I already posted this in the Audio forum, since it is considered an Audio operational amplifier. However, I am not using it in an audio application. So as to not double…
Other Parts Discussed in Thread: DAC11001A , PGA202 , PGA103 , PGA280 , PGA281 , OPA4182 , OPA4191 , OPA1604 I am looking for a PGA for the output from DAC11001A to be able to output up to +/-10V, but also take a 5V output down to 0.5V. Do you have any devices…
Part Number: TPA3129D2 Other Parts Discussed in Thread: OPA1604 Hello Team,
My customer is having a Problem measuring the output of the TPA3129D2. When they try to measure one of the Outputs with an oscilloscope, they get weird behaviour from the chip…
Fair enough, thank you for the additional information about the desire to further increase dynamic range of the front-end.
OPA1604 is our lowest noise quad, with OPA1664 in 2nd. The OPA1654 is a good quality CMOS offering as well.
There are more choices…
Hi Mateusz,
in the following I try to explain a bit how the supply filter should be designed.
First, the OPA1622 shall be discussed. Assume a unity-gain buffer with an output signal of 1Vp sine into a load of 32R. This gives a load current of 31mAp…
Part Number: TPA2005D1 Other Parts Discussed in Thread: OPA1604 , , TPA6211A1 , TPA2025D1 , TPA2080D1 , TPA6205A1 , LM48310 Hi,
I am using, OPA1604 high performance audio op-amp, (soundplus series has very less THD and noise figure). Next stage is audio amplifier…
Hello Tapas,
Adding a coupling capacitor in the signal path before the 4th stage will remove the offset from the previous 3 stages. Then, only the offset of the 4th stage will be present at the output of the signal chain. The coupling capacitor at the…
Other Parts Discussed in Thread: OPA1604 , OPA4227 Hi,
My customer is looking for a replacement to the obsolete part- LME49740 and would like to know if OPA1604 is the best fit or if TI recommends another part that is better?
Thanks,
Soumya
Hi Daniel,
Unfortunately the only document available for this device is the data sheet.
In addition this device is no longer in active state. So if you're looking for a replacement you can take a look at OPA1604 for a SOIC replacement and OPA4227 for…
Part Number: OPA134
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…
