Title: OPA275
Post by: petemoore on June 10, 2004, 01:21:29 PM
The latest TI bulliten advertises these chips.
 Anyone try them yet?
 Do they drop in a standard dual OA socket?

Are you sure that's the #? I tried it at Ti.com and their search engine doesn't recognise that #.

Analog Devices has a OP275. I got a couple to build a Black Cat OD. It's just a standard dual OA.

Are you sure it's not this?

I deleted/am not going to find that newsletter I got today.
 Yes that's probably the it, or close enough for this topic.
 The one I looked at was CMOS.
 This one you've provided the link to looks interesting enough to type about!
 Ever heard of these being tried in say..an HMP or SD-1, or dual opamp socket in an OD/DiST?
 Application notes are vague, more likely I'm not looking at them right. I didn't see the pinout.  
 Will this dual CMOS do well as a 'plug in and try', in a circuit wired for a standard dual opamp?

I have some OP275 from analog devices.  Sounds very clean and nice in a TS type circuit.  

I don't know anything about OPA275 though.
