Many years ago, we made an effort to provide detailed over temp and process AC spec limits. That was using process case limit libraries and their temp effects. Designers and management hated this, so it was dropped, but if you want to see an example …
Part Number: THS3491 Other Parts Discussed in Thread: OPA2677 Hi Team,
Please advise on the following question.
I consider to use THS3491 in a system which requires stringent HD2 and HD3 performance.
The THS3491 datasheet insists HD2 and HD3: Less Than…
Hey Carl, I got to ruminating on other ways to do this and I remembered this very ubiquitous (but somewhat secret) active impedance differential driver that is used throughout the DSL industry. Here, with cross coupled feedback, we can create more output…
Going a bit further looking at the DC level shift current for the CM control,
Operating the OPA2677 midscale DC to get the best headroom on the signal - 2.5V here,
The AD9637 wants to se a CM input (provided by the FDA control) of 0.9V.
If we use 1kohm…
Part Number: THS3491 Other Parts Discussed in Thread: BUF634A , OPA2810 , OPA2677 , TINA-TI Hello,
I am working on the design of an active filter I need an operational amplifier powered in 15 volts and injecting a high current ideally 500mA; I selected the…
Part Number: OPA4140 Other Parts Discussed in Thread: OPA140 , OPA2677 , , TL072 Hi team, I'd like to know about the minimum value of the slew rate. Of course, I know this value is not specified in the datasheet. (Just write TYP) I'd like to know it for our…
Of course Anber the THS3491 (highest slew rate CFA out there) can do this.
There are many lower Io CFA's that can also do this on +/-6V supplies for these non-RRO solutions.
OPA695 comes to mind. LMH6702 is a close alternate - duals might be the OPA2677…
So your topology looks good, we did all those parts back in the early 2000 time frame, if you switch to the OPA2677 dual, it will do this easily on a single 7.5V supply. Those DSL drivers were not RR out, but can crank a lot of output current with minimal…
Hey Danilo, look at the OPA2677 which is a dual CFA which has your current requirement on single 5V supply. For unity gain, you will need a feedback R of about 600ohm for stability.
