Part Number: OPA743 Other Parts Discussed in Thread: TINA-TI Tool/software: TINA-TI or Spice Models I am an experienced Pspice user but just trying to learn Tina TI. I have entered the Wein Bridge example circuit. I got the transient analysis to work and…
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 application…
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 is…
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.
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 this…
Hi Lisong,
I am sending you some training materials developed by our analog applications group that provides information about operational amplifier parameters including Input bias, current offset current and offset voltage. You will be particularly interested…
