Part Number: DAC7750 We have designed a board using the DAC7750 powered by +24V(AVDD) and +3.3V(DVDD).
The board is powered by another board through a DB25 connector which provides these 2 rails (+24V and +3.3V)
Our design was working well, till an engineer…
Part Number: DAC7750 Dear All,
I'm using the DAC7750 converter in a design to output a 4-20mA signal with a update rate of 4kHz. I first implemented the basic feature (only DAC, no watchdog, no slew rate, no control, ...). After successful results I added…
Part Number: DAC7750 In the DAC7750 Datasheet SBAS538B –DECEMBER 2013–REVISED JUNE 2016 in table 7.3 Recommended Operating Conditions it says:
Loop compliance voltage Min 4.95V Max 5.05 V
and
Reference input voltage Nom 30 μA
This is obviously…
Hi Kevin,
After little long delay I again started working on dac7750. This time the Crc is implemented and tested.
Thanks for the guidance you provided.
Going ahead with the development I had some observation , while reading the status register continuously…
Part Number: DAC7750 why are there two TVS diodes in typical application circuit of page 36? The right TVS is turned on, and the IOUT is shorted to the ground. The IOUT cann't ouput 4-20mA, can it?
Other Parts Discussed in Thread: CC3200MOD , DAC7750 For a sensor device i use 2 DAC7750 in daisy chain together with a CC3200MOD. The first versions of the board use the CLR Signal of DAC7750 to reset the device during power up once.After a redesign i…
Other Parts Discussed in Thread: DAC7750 Hi team,
Here is a question from a customer when using DAC7750. When we are sending read command and reading back registers, the returned value is always the same as what we send:
Channel 1: SCLK; Channel 2: SDO;…
Other Parts Discussed in Thread: DAC7750 , DAC8750 Hi,
I have a question about SPI Shift Register at DAC7750. SPI frame is described In datasheet page 23.
I think that this is for DAC8750. I think that it is 20-bit input frame consists of an 8-bit address…
Other Parts Discussed in Thread: DAC8750 , DAC7750 Dear Sirs
Why the TUE of DAC7750 and DAC8750 are the same (0.1%)?
12- Bit :DAC7750
16- Bit: DAC8750
Should the TUE of DAC8750 be better?
What is the accuracy difference between DAC7750 and DAC8750 ?
I am u…
