Hi Haritha, VA19 should come first and be used to enable the VA11. Then use the VA11 power good to enable the VD11 supply, and then use the VD11 power good to enable the VLVDS supply. Thanks, Chase

Hey Angel, We swapped the capacitors from 10nF to 1 μF as you recommended. Here is our new connections: We also tested the voltage across the 1.65k reference resistor and with CFG2_IDAC_500UA we measured 0.85V. We also measured with different IDAC values to be sure that the IDAC is working. For exampe with 1000uA we measured 1.69V. Yet still, with these changes we only receive full-scale values. Here is console prints of our test program output(Configuration registers, Raw ADC data)

Let me check that .

Also want to just confirm that any kind of configurations which need to be done are possible through ADCs SPI communication right!?

Yes .. It is AFE's spi write only.

Part Number: ADS1278EVM-PDK Tool/software: Hello, here is a detailed description of which parts I am using and what my problem is: I'm using the ADS1278EVM-PDK eval board (An older version from 2011, can be seen on atached photo). The eval board is also connected to the MMB0 motherboard. The Motherboard is only connected to power and not also to the software via USB, since I want to create a different external communication directly from the eval board. When setting all the switches and jumpers to SPI mode (in all different configurations) the communication does not seem to work correctly. The main problem seems to be the FSYNC/DRDY pin on the chip itself, as it only stays low or high depending on the configuration and does not act as some sort of SPI chip select as I understand it should from the datasheet. The onboard clock works, as do the Digital out pins that output some data, but without the FSYNC/DRDY pin working as the SPI chip select I do not know how to parse the continous digital data coming out. It may also be relevant that the board works completely fine in the FS mode and connected via USB to the TI software. TLDR: I would like to use the eval boad in SPI mode without the motherboard (or only using the power from the motherboard) and connect the output to some other device for digital data reading (for example raspberrypi).

Okay great thanks please let me know the above details

Part Number: TLV2553 Tool/software: Please provide life cycle status for part TLV2553IDWG4 . It is given active in recent datasheet version but not found anywhere on HTML page. Kindly confirm if the part is still active or discontinued

Hello Tom, I need to sample the following : 3 phases voltage, 3 phases current on a socket A, 3 phases current on a socket B. The CPU shall compute the power factor so I need to measure, on each phase, 1 voltage and 2 currents. In order to compute the angle between each phase, I also need to measure all 3 phases simultaneously.

Hi Ryan, Please find the attached files with the dual channel configuration functions. e2e.ti.com/.../afe4960_5F00_drv.c e2e.ti.com/.../afe4960_5F00_drv.h

Part Number: AFE58JD32 Tool/software: Hello, I'd like to ask what is the maximal sampling frequency at 12 bits resolution for 2-lane JESD configuration? Best regards, Mateusz Walczak

the yellow is RVS, the blue is CS

the yellow is RVS ,the blue is CLK

the yellow is RVS ,the blue is CNT

I have created a program to output the signal collected by ADS9110 using DA. Below is the waveform of the output

the yellow is DI, the blue is CLK

the yellow is RVS, the bule is reset The RESET signal is only sent once when powered on

the yellow is CLK, the blue is CS

Part Number: ADS7138 Tool/software: Hello experts, We want to use ADS7138 to the satellite project. Are there any restrictions on using it on satellites? Best regards, Toru Kimura.

Part Number: BP-DAC11001EVM Tool/software: HI! Could i get a BP-DAC11001EVM PCB file. I want to refer ground plane.
