Part Number: DAC8871EVM Hello,
I have a problem, I don't have voltage on output. Do you see a problem in my schematic in attachment.
I drive th chip with arduino. See code below :
IOWrite(GPIOA, CS_DAC3); delay(10); SPI.transfer(0x4f); // config0…
Part Number: DAC8871EVM Other Parts Discussed in Thread: DAC8871 , Me and my senior design team are having trouble getting the DAC8871 and DAC8871EVM to function. When using the DAC8871, we are not getting an output when sending data which we would expect…
Nishant,
Your summation is correct. The supply is not injecting a fixed current to the EVM. It is providing a fixed voltage with a programmed current limit. If that current limit is reached, the supply voltage will begin to droop. Otherwise the supply…
Part Number: DAC8871EVM Other Parts Discussed in Thread: DAC8871 , DXP , DAC8811EVM Is there a simple SPI interface converter (USB-SPI) for use with evaluating the DAC8871 EVM?
Thanks,
Dan
Part Number: DAC8831EVM Other Parts Discussed in Thread: DAC8871EVM , , DAC8831 , DAC8871 , DAC11001A Hello Team,
It is possible to control the output of the DAC8831EVM, DAC8871EVM and DAC11001A-EVM per normal SPI code from a Arduino library? I mean…
Part Number: DAC8871 Other Parts Discussed in Thread: OPA211 , THS4011 , OPA211A , THS4304 , OPA277 Hello,
In the customer, the settling time from +10V to -10V is about 15us. -10V to 10V settling time is about 1us. In the datasheet, both settling time…
Kevin, thank your soon answer .
DAC8734EVM-PDK does not exist, this DAC is similar to DAC8871, the only difference, it is four channels. The question is:
As you know the MMB0 motherboard can be used with the EVMs listed in the DXP web page. If I bought…
Hi Luis,
Which figure are you referencing; Figure 39 or Figure 40? The op amp I would strongly recommend having would be the OPA2277 on the reference line as shown in Figure 40. The stability we are talking about is including a Riso to have a capacitor…
