Other Parts Discussed in Thread: TINA-TI, TLV9064
Any another OP-AMP if available?
Please see attached circuit diagram(PDF) using TLV9054. I added 7 times amplifire with filter, however at less than 0.022uF for C13, I observed oscilation.
I would like to put C13 much smaller since this capacitance seemed to make total responce rather than cut off frequency of filtering which is around 35kHz.
Any much stable op-amp than 9054? The power is 5V, Temp range is -20 to 85 degC.
Please advise.
BEST REGARDS,
