Part Number: TIPD125 I'm working with a TIPD125 evaluation board populated with all recommended components from the application note (SLAU525).
I've hooked the board up to a Teensy 3.6 for SPI comms and have correctly connected a +/-15V supply to VCC…
Part Number: PGA281 Other Parts Discussed in Thread: TIPD125 , , OPA596 , INA592 , INA240 Tool/software: Hi Team,
I am looking for high side current monitor solution to measure ~10uA level current at 48~60VBUS.
The close solution I find is the reference…
Hi Dejana,
You can use the circuit mentioned in the attached link for generating bipolar output signals from Unipolar DAC.
What is the frequency of signal you are generating?
For the output Op amp key specifications you should look for as follows…
Hi Koji,
Sorry, I forgot to link in the TI Design I referred to in my previous post. I have linked it here.

It means Both Resistance & capacitance feedback.
kai klaas69 said: To make the circuit immune against capacitive loads?
Yes sir.
Actually i referred this circuit from the attached…
I'm going to use the DACs in TMS320F28377S based on the application in the documentation TIPD125 therefore I'll disable the buffer in DAC. I have read documentation SPRS881, SPRZ422, SPRUHX5, SPRUH430 but there are no more information about how using…
Jose,
Given the requirements that you've shared so far, I think the most cost-effective solution is going to be a discrete approach using a DAC followed by an amplifier to apply gain and offset. This also easily accomodates using a 3.3V interface. …
Matthew,
We don't really have any application note explaining how to perform analog calibration as it sort of varies from one device to another since DAC architecture and other parameters can vary.
For something like this I would most likely look…
Hi Jingtai,
This TI design is from precision data converter group it show how to convert unipolar output of the DAC to bipolar.
However if you want to use high speed DAC with high output voltage swing, please refer to following ti designs.
…
Jingtai,
From glancing at the TMS320F28377S datasheet it does not appear to me that the internal DACs implement a multiplying DAC architecture, most likely they are string DACs which are architecturally different. I would refer you to these blog posts…
