And, I think I finished scanning the TI product trees for post 2015 <50MHz Introductions - omg, this is quite impressive, lot of work here to fill in the parametric fields, but this is the list I came up with the slightly modified descriptions - this…
Hi Ella,
I think U3A/B/C/D/Q1 will have some delay because of the limited bandwidth. But I am not familiar with amplifier and BW. Maybe you can create one more threat to ask for expert responsible for OPA4377 for help.
Best Regards,

Thanks Helen. I'd like to minimize complexity and keep BOM cost as low as possible (the OPA4377 are $3.98ea in Aus). Is it possible to remove the amplifier and connect the output of the MCU DAC directly to the gate of Q1? What are the risks of a direct…
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…
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also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

Hello Aldo,
Take a look at Fig 2 in the attached .pdf which shows a L/R audio envelope circuit that's used as part of an audio envelope tracking power supply design. If your design uses only one channel, then you could eliminate one of the input OA…
