Hardy,
Most op amps, including OPA4379, have reverse-biased ESD protection diodes between each pin and power supplies. For that reason, the input terminals voltage absolute maximum rating is specified up to 0.5V beyond the rail and if you exceed this…
Other Parts Discussed in Thread: OPA4379 1007.PB_FA1-001.pdf
In the circuit we are using OPA4379 to close the feedback path of a switching regulator. Among about 40 units one of them is suffering from pulse width jitter issue. Our debugging work confirmed…
Hi Herman,
Thank you for your prompt reply. Using TINA TI v9, I found a basic design utilizing the TLV379 having the spice model. We have run circuit design simulations already. The results were as expected. This morning I got a nice email from Gustaf…
Hello Yonatan,
I am assuming the 80uA is for all four amplifiers (20uA max per amplifier) in a "PW' (TSSOP-14) package:
GPN
VosRoomMax (mV)
IsMaxCh (mA)
GbwTyp (MHz)

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also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.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