Other Parts Discussed in Thread: OPA338 Hi all,
I am in need of some help,
I cannot find the compnent above (top left IC) in the TI catalogue.
It is supposed to be am opamp, but I could only find the OPA338, which doesn't come in the package…
Nathan,
In general, op amps, bipolar transistors, JFET transistors, and CMOS transistors will have lower noise when current is higher. Basically, noise is a trade-off for power consumption. Below is an article that covers the theory behind this. Look…
Hello Iwata-san,
Please see rule of thumb #2 in the attached article for an explanation about how noise increases with temperature.

The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

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…
