Part Number: DAC8734EVM Hi Team,
This post still related to this e2e link:
Our customer still looking for an alternative hardware of MMB0 to evaluate the 8734EVM module. Can you please recommend hardware side that can be used a replacement for…
Part Number: DAC8734EVM Other Parts Discussed in Thread: DAC8734 , DAC7734 Hi,
I just bought a new DAC8734 EVM board.
I try to powerup the DAC8734 considering the powerup sequence given in datasheet.
At first I connect the DVDD (+5V) and IOVDD …
Part Number: DAC8734EVM Other Parts Discussed in Thread: DXP Hi Team,
Good day,
The DAC8734EVM is an evaluation module built to the TI Modular EVM System specification. It mention in the user guide that it can be connected to any modular EVM system…

Hi,
We have a load that needs a variable low noise programmable voltage between ±5V with around 250mA (we are using an op-amp buffer to support the current draw) .
We are…
I'm a student doing research and haven't dealt much with SPI, but I talked to the engineer who is over our shop and he said that it is most likely caused by a lack of MISO feedback from the board to the micro controller. Would this signify a broken board…
Part Number: DAC8734EVM I have set up an SPI bus interface between a PSoC 5lp processor and a TI8734EVM board. I can write perfectly to all four of the 8734 DAC channels. However, when I send a read command querying the DAC input registers (or latch registers…
Uttam:
Thank you for your reply.
I found the Gerbers for the DAC8734EVM board attached to another forum post.
If you policy is to not offer the Gerbers to your customers you should modify this document ...

Hi, using 3v3 microcontroller with SPI clock at 500kHz for debugging. Clock idles low. Data changes on rising edge. Here is sample logic trace:
Board jumpers are in default positions. Gain of 4 on DAC channels. /LDAC is pulled…
Part Number: DAC8734EVM Other Parts Discussed in Thread: DAC8734 Hi, I have purchased two DAC8734EVM modules and have (almost) the same problem with both.
The first draws too much current (I've set the output on my power supply to max 50mA) from AVdd…
Other Parts Discussed in Thread: DAC8734EVM , CC3100MODBOOST , CC3100 It would seem the serial interface would still be open for the DAC8734EVM after using a CC3100MODBOOST on a LAUNCHXL-F28377S, but wondered if there may be a problem?
