Hi Dan,
Apologies for the confusion, I did not catch that with my response. Yes, R3 would be the current limiting resistor in this case and it is large enough there is no major concern on the amount of current that would be input into the op amp.
Thanks…
Part Number: OPA2677
Hello,
the TI page for OPA2677 provides design resources, see here:
www.ti.com/.../OPA2677
This page offers links to download CAD/CAE symbols and footprints for all available packages. I'm interested in the HSOIC (DDA) package. The…
Of course, the 12V OPA2677 can't do as much voltage swing as the BUF634A,There are 30V DSL line drivers also that put out quite a lot of current as well, but no where near the OPA2677
Hello Mojtaba,
If you go to your TINA-TI SPICE simulation and either "click" or "double-click" your OPA2677, you can select "Enter Macro" and view the pin assingments in the SPICE model.
For the OPA2677 SPICE model a Disable…
Part Number: OPA2677 Hi team,
I am looking for a high output current amplifier for my mobile phone customer. They are requiring the amp:
1. Output 300mA current on 5 ohms load;
2. The bandwidth need to be over 100mA;
3. The package need to be BGA or QFN…
Part Number: OPA2677 Other Parts Discussed in Thread: TINA-TI The OPA2677 is getting really hot after power up. I think the part is latching up. I'm using +-6v power rails and I have 0 volt input and no load. If I disconnect the thermal pad the problem…
The OPA2677 will deliver over 1 amp, not shown in the datasheet, but later testing showed that. This was K.20 testing by Alcatel where this emulated lightning strike on a phone line showed about 1.7A supported by the OPA2677
Other Parts Discussed in Thread: OPA2677 , DXP Hi everyone,
I need OPA2677 IBIS model for doing the Signal Integrity Analysis. I couldn't find the IBIS model in the TI website. Could you please design IBIS model for this part?
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 …
Other Parts Discussed in Thread: TINA-TI , OPA2677 I'm attempting to simulate a differential line driver circuit using the OPA2677. The TINA-TI model for this part, when instantiated within TINA-TI, is missing pins 5, 6, and 7. This is the non-inverting…
