I am looking for some informations regading the process FAB Technology of the opa1642-q1 :
-The Mask SET / The die Revision . -How we can get easily the FAB Site / The Diffusion Lot /the Wafer N°
Those requested datas…
Part Number: OPA1642-Q1 Other Parts Discussed in Thread: OPA1642 Hi team,
There is an analog mic in and with 2 meters cable to the OPA1642.
Do you have recommend solution for long trace audio differential signal and protection with short to VDD…
Thank you, Alexander. Can you verify if the OPA1642-Q1 is just a screened version of the OPA1642 or if it is fundamentally different in the manufacturing technique?
Hi Sherry,
There is no other Q1 headphone amplifier at this moment, let me check if we'll have something new. In addition, can customer use digital input instead of analog inputs? If they can use digital input perhaps TLV320AIC3254-Q1 can be an option…
Hey Ron,
Yeah, the OPA1656 will provide an additional 1.25V of headroom going to the positive rail. It can go to the negative rail but not below for the linear range.

I put together a table below showing devices that have high…
Hi Dongbao,
I think the addition of a .1uF cap very close to VCC is a good idea. Below is a couple examples of the LP filters you could implement.
You could consider the OPA1642-Q1, though I would suggest you ask the opamp forum to see if there…
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…
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…
