Hi Yuting,
Thank you for your reply.
You mentioned for setting the LED current.
In this case, it is determined by current limit(2Atyp) and R1.
I can understand at this point.
Could you please explain why are there the recommended operational value(SOT…
Part Number: OPA860 Other Parts Discussed in Thread: DEM-OTA-SO-1A , TINA-TI Hello,
I've expected to use operational transconductance amplifier (OTCA) OPA860 in my design as a wideband voltage to current converter (from a standard 50 Ohm equipment, and…
Part Number: OPA820 Other Parts Discussed in Thread: DEM-OPA-SOT-1A , , TINA-TI Hallo,
I can not verify the Noninverting Pulse Response in our applikation.
VCC=6.2V...10V, VSS=-2V, Gain=+1, Pulse Signal High Level 4.6V, Pulse Signal Low Level 1V

Hi Boggarapu,
Most bucks can be converted to an inverting buck boost topology by following a couple steps. Please refer to the guides attached. Let me know if you have further issues.

Hi Orwell and welcome to E2E,
What type of diode are you using and what is the desired hold time? I recommend building a working circuit in TINA-TI before you spend the time and money to put it together on a PCB. Look at page 3 of the OPA615 datasheet…
Part Number: DDC112 I am designing an instrument based on the DDC112 as a student project.
The lower part of figure 29 in the datasheet shows the DVDD power supply derived from the AVDD supply with a < 10 ohm isolation resistor. I would be grateful if…
Hi Simon,
I was double checking my test setup from yesterday and noticed that I was using the incorrect low-pass filter setting in the AP, I corrected it and got the following results:
I tried 2 different configurations with the same results, using…
Hi,
Yes, you can use the OPA699 in a standard difference amplifier configuration to use differential inputs. It's hard to estimate the exact propagation delay and it will depend on if you are hitting the limiters or not, but I would expect in the range…
Part Number: OPA860 Other Parts Discussed in Thread: OPA615 , DEM-OTA-SO-1A Hi,
Attached is the sample&hold circuit with OPA860, but the result is not correct with TINA simulation, please give me some advice. Thank you very much.
