Dear TI Sir
My customer had used LMV604.
Due to LMV604 Supply Current is too high, he would like to search another one to instead of LMV604.
Topic spec.
Supply voltage(V+) – (V–) : Vmax = 5.5 V
Input bias current : IBmax = 1 pA
Supply current…
Hello Scot,
While I have never constructed such a circuit myself, I don't see why it wouldn't work. For the input stage amplifiers you will want low input bias current. the LMP7721 is an ultra-low input bias current amplifier (just 3fA) and has very…
Hello Gilbert,
Looking at the schematic and scope photos, most likely it is due to the fact that the TLV2404, which is a nano-power (900nA) op-amp, just cannot drive the feedback and output loads.
It has a very "weak" output stage (200uA max). It…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
