Anuraj,
There is no danger of OPA343NA being obsoleted any time soon. However, please be aware that there is no similarity between TL343 and OPA343. A former part is on a bipolar, high voltage (30V) process, with GBW of 1MHz while the latter one is…
Hello Amruta,
I can help you with the OPA355 and OPA343 op amps. Note that the HBM and MM numbers are the same for the various suffixes you listed:
OPA343 HBM 500 V MM 100 V
OPA355 HBM 4 kV MM 500 V
The DIT4096 is a digital audio transmitter and…
Vishal,
For the DC level shift you may be required to use rail-to-rail input op amp; any of the following op amps is offered in PDIP package with rail-to rail input common-mode: OPA340, OPA343, OPA344, OPA347 and TLV2451. You may request free samples…
Hi David,
Let me discuss this with some of my colleagues to see if we can come up with suggestions for a test that will help you screen for products which may display this behavior.
There's a few things in play regarding why some devices perform this…
Pablo,
Since all the input and output range specifications are referenced with respect to supply voltage, your conclusions about the input common-mode voltage range of OPA1642 and OPA227 are correct. However, when it comes to OPA227, you overlooked…
Other Parts Discussed in Thread: OPA171 , OPA141 , OPA140 , OPA343 , OPA314 , OPA365 , OPA377 , OPA376 , OPA337 , OPA347 I use the OPA171 in current limiter of an input circuit. The circuit operates in two modi: a closed loop and an open loop. Closed…
Hi Sravya,
Attached is the C2000 PCB design guide PDF and very good to review even if you are an avid PCB designer.

The attached presentation is where much of the methods for choosing the right R-C and Op Amp to drive a CDAC SAR converter were derived from. Look it over to help understand where the rules of thumb for op amp BW came from.
Let us know after studying…
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also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.
