Hello,
I figured out what was wrong with this ESD issue. I had too strong and un-calibrated ESD source. I pushed complete design above the ESD limits. After several testings with calibrated Teseq NSG435 ESD gun, the product has 8kV-contact/15kV-air…
Part Number: OPA1678 Thanks .We have used the opa1678 for Automobile audio, we want the POWER and the output ues one line,as follow:The automobile give us 8V (DC),then it get sounds(AC) from the 1678.
We wang Frequency Response as the attachment …

The OPA1678.tsc works normally for 25KHz BPF, but the replacement of the OPA170 works abnormal. What is wrong? OPA1678.TSC OPA710.TSC
Part Number: PCM5102A Other Parts Discussed in Thread: OPA1678 , LM27762
Hi,
Sometime ago I asked you a question about possibility of using op-amp with PCM5102A to have higher Vrms at lower loads than 10k and you recommended me to use something like…
Hi na na78,
I'd suggest the following circuit:
This will give you 55dB out to a 32kHz (52dB, or -3dB point). In order to use the OPA1678 as a noninverting buffer in this case, you'll need to bias the input to mid-supply. However, if only the noninverting…
