Hi Aubrey,
We typically use transient analysis which is a little more straightforward; we don't have much experience with the oscilloscope function. I think you are right that there are some undocumented "features." For further assistance on using…
Other Parts Discussed in Thread: OPA743 If anyone have the data about electrical characteristic of ESD diode in input port of OPA743, let me share.
I just have allowable input voltage and current spec. in datasheet, so I need more information for my…
Hi Kareem,
I suspect that you are loading the OPA743 output too heavily with the component values you have selected for the Wein-bridge elements. The output of the OPA743 sees the two 17.5 Ohm resistors in series to ground, and also the capacitor reactances…
Other Parts Discussed in Thread: OPA743 , OPA4243 Hi, I'm new to power management and am currently designing circuits to manage 12v power input from adapter. The voltage coming out of wall is around 12v and I want to use OPA743 to buffer it. Can I use…
To anyone reading this.
I uninstalled the version on the pc & REDOWNLOADED and reinstalled tina-ti.
On looking at the macro for the opa743 is see its quite different, so i'm not quite sure what went wrong with the previous installation.
Part Number: OPA454 Other Parts Discussed in Thread: TINA-TI , , OPA743 , OPA552 , OPA452 Tool/software: TINA-TI or Spice Models Hello, i am comparatively new to this analog part of the world and usualy deal with power supplies' designing for the embedded…
CK Ho,
TLV2370, OPA743 and OPA191 are few options with high voltage (>12V) supply capability, comparable specs and RRIO. But these are not directly P2P compatible with LM321. You will have to swap your Pin1, Pin3 and Pin 4.
Lets us know if this…
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also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.
