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…

Hello Lance,
We do offer the DEM-OPA-RGV-EVM , which is an generic EVM board designed for VQFN (RGV) package PLC and DSL line drivers. The associated user's guide showcases the EVM functionality, which can do either two amplifier channels or a single…
Hi Nishie,
Yuta Nishie said: 1. Am I correct in understanding that these specifications also apply to DC (constant voltage) inputs? (Do you mean the DC offset is 0.2V?)
This is a simple way to think of it. Realistically, the device is non-linear…
Joaquin,
There is an EVM available which you can get from TI.com to test yor circuit (link below)
https://www.ti.com/tool/DEM-OPA-RGV-EVM
In your schematic (snippet below) the input swings from 0V to 3.3V, so for the time period in which it is 0V…
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…
Hello Demian,
I was able to find unpopulated EVAL board Altium projects DEM-OPA-SSOP-3A, DEM-OPA-SSOP-3B, DEM-OPA-SSOP-3E, but not DEM-OPA-SSOP-3C and DEM-OPA-SSOP-3D. All of them have the same package, but different pinouts. The closest one to C and…
Hi Kristoffer,
Sorry about the delay here. An example script is as follows, from the EVM user guide as well as my own clocking script:
w a0 00 00 # Set page 0
w a0 01 01 # Software Reset
w a0 02 09 # Wake up with AVDD > 2v and all VDDIO level
w…
Shrikant,
You are correct, the pinout for the SLOU055 board is meant for a pin-out similar to the OPA2836. The evaluation module for the OPA2889 requires the use of the DEM-OPA-MSOP-2B EVM. If you can work with 5V supplies then the OPA2836 can be used…
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…
