Part Number: OPA1678 We have used the opa1678 for Automobile audio, we want the Frequency Response as the attachment {Frequency Response of OPA 1678 }，but the actual Frequency Response as hte attachment {The actual Frequency Response }.We dont know 3005…
Part Number: OPA1678 Other Parts Discussed in Thread: TINA-TI Tool/software: TINA-TI or Spice Models Hi sir,
The following are 4th LPF requirement:
center freq=60Hz, stop-band 400Hz-30KHz @ -40dB at least
input waveform: 5V 60Hz square wave, output…
Part Number: OPA1678 Hi Team,
Good day.
My customer is looking for the Output Current at 1V drop. We are looking in the datasheet and couldn't find this information.
Regards, Renan
Hello Bogey,
An op amp really isn't the function to accomplish the waveform you propose. Modern applications take advantage of Arbitrary Waveform Generation technques to generate complex waveforms such as yours. It is in its simplistic description is…
Part Number: OPA1678 Hi there,
We are considering using opa1678 as preamp of a pvdf audio sensor. Since there exist silver migration we do not want to put bias voltage to pvdf and thus figure35 in the datasheet is a good start.
1. With above R5&R6…
Part Number: OPA1678 Other Parts Discussed in Thread: NE5532 , Dear TI,
we want to use OPA1678 to replace NE5532, but it sounds NE5532 is better performance than OPA1678.
could you help to provide the differece between them?
thanks a lot!
Part Number: OPA1678
The OPA1678 noise is spec'ed for 4.5 nV/sqrt(Hz) at 1 kHz.
Using the following circuit in TINA, where the VG1 source = 0V,
and performing Analysis->Noise Analysis->Total Noise returns this result:
I expected this value…
Part Number: OPA1679-Q1 Other Parts Discussed in Thread: OPA1678 , OPA1679 , TINA-TI The datasheet for OPA1678 specifies -V. I've looked hard through the OPA1679 datasheet but do not see a signal specified. I was curious to know if GND can be used instead…
