Part Number: DAC80508 Other Parts Discussed in Thread: OPA4388 , DAC81408
Hello,
I have a customer that wants to use the DAC80508 with a load potentially as low as 66 Ohm. When the output is at full scale 2.5V, this could result in ~38mA.
I'm confused…
Hi Charles,
OPA388-Q1 is the automotive version of OPA388/OPA2388/OPA4388.

hello Charles
Are you using the quad? AD8630. If so, then I would recommend the OPA4376-Q1. It is not a Zero Drift device but it is trimmed and offers very good DC performance. As far as choppers, we have the OPA2317-Q1 as low cost solution (dual) and…
Morning Alex,
yes, the way you have this connected will give a negative going output signal - These opamps can work fine with negative supply but it is unlikely your ADC will want that polarity. More likely you will need to operate positive supply only…
As I mentioned before, a modern higher precision replacement for OPA4277 would be OPA4188. But if you can use 5.5V supply (absolute max 7V) and tolerate higher IQ, the best alternative would be OPA4388.
Ok, so your total gain is 104kohms and we need to split that between Zt and FDA stages. I will set this for 50kohm input Zt and 2.04V/V FDA gain with a 3rd order filter there to define BW as the Zt stage will vary with source C.
I am not sure you…
Part Number: OPA4350 Other Parts Discussed in Thread: OPA828 , OPA4192 , OPA4376 , OPA4388 Hi, I was wondering if there is a newer component to update OPA4350EA/250 OPAMP? A replacement component that has better characteristics.
Thank you.
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…
