Part Number: DAC7728 To whom it may concern,
I would like to clarify a point regarding the DAC7728. I am referring to "Table 7" under "OFFSET DACs" in the datasheet. The table lists "-10V" for the "DAC CHANNELS MFS VOLTAGE" when the "OFFSET DAC CODE…
Part Number: DAC7728 Other Parts Discussed in Thread: DAC8728 , DAC8228 Regarding the TI DAC7728SPAG, the datasheet state:
The DAC7728 must have ample supply bypassing of 1uF to 10uF in parallel with 0.1uF on each supply,located as close to the package…
Part Number: DAC7728 Other Parts Discussed in Thread: TMS320F28379D , Dear Sir,
I wanted to use DAC7728 with the controller. I need to know that the timing requirement of the DAC is compatible with TMS320F28379D or not ?
Do I need more components…
Part Number: DAC7728 Will the DAC7728 work properly if it is not brought up in the sequence outlined in the datasheet? I am having a problem with being able to sequence the AVss rail as it automatically comes on. The datasheet says the digital initialization…
Part Number: DAC7728 I am able to write to a single DAC channel and get the output I want, and I am able to read back the value written to the register. When I try and write to the next DAC after that I get no response from it and the output voltage doesn…
Part Number: DAC7728 Hallo,
I need some help with the DAC7728.
I need to simulate different voltage levels in an isolated environment (via opto-couplers). The power supply is also made potential-free. I try to program the DAC in following steps: …
Part Number: DAC7728 After completing our Alpha design, and 10 units, we found the DAC range we need is much less than anticipated. However the precision we need is higher. We are using a 1.024V reference with a 4x multiplier. So our DAC output is 0-…
Part Number: DAC7728 Hello, I have design a pcb board, which 2 DAC7728, my configuration:unipolar output, i don't use the correction engine, 15V for AVDD, IOVDD is connected to DVDD and is 5V, i dont use LDAC Some time one is not starting (all time the…
Other Parts Discussed in Thread: DAC7728 , OPA2277 Hello,
I made a board with a DAC7728 , used in bipolar mode (±15V). Vref is 2,5V, gain is set to 4x.
But some of this chips is fired in some PCB boards. I found the fired line is ±15V. So, I am afraid…
