Hello Vijayalaxmi,
It seems like LM2662 or LM2663 can perform the task you are looking for (creating a -2.5V supply from +2.5V) and can put out 200mA of current and has the same pinout as the TL7660 in the SOIC (D) package. I'm not sure what TL7660…
Hi Manabu,
Sorry, I had mistakenly uploaded / linked to the wrong documentation.
I have attached the correct documentation here for your reference:

Hi Di Wang,
I was able to resolve your Convergence problem (which I also observed) in TINA-TI by selecting Analysis, Set Analysis Parameters, Shunt Conductance (S)= 100m (was originally 0).
In addition, in the same panel, I was able to improve Step…
Hi Xiaoc,
The TLV3201 input CM voltage range goes beyond the V- to V+ range (e.g. from -0.2V to 5.2V when operated off a single 5V supply):
So, you can use the part, I believe.
Most parts specified for 5V single supply, would also work with +/-2…
Hi Joel,
Here are my comments:
1. Minimum Stable Gain: What LMH6629 package are you using? If SOT23-5, then you must raise the gain in the front end (U1, and U2) and also for U3 as the SOT23-5 package is for minimum stable gain of 10V/V or higher…
Hi Kawai-san, The 50ohm series output resistor is a desirable thing to have when probing the output as it isolates any cabling / connector parasitics and provides a 100ohm (=50+50) load (which is how the LMH6502 was characterized, mostly). Just factor…
Hi Kawai-san,
You are correct that the LMH6502 model is not well-suited for single supply operation / simulation . I tried to setup a TINA-TI simulation file for the LMH6502 configured for single supply but I'm running into issues. Namely, even if I…
Hi Kawai-san,
