I am attempting to generate an output signal biased at 6V with a swing of 2.4V (4.8V to 7.2V). Since the datasheet for the AD5449 states that IOut2A and IOut2B "should typically be tied to the analog ground of the system, but it can be biased to…
I am working with a AD5449 DAC, interfaced with BF561 via SPORT1 on a custom board. I am facing an issue where the DAC fails to respond to the commands from the DSP.
Failure when power on reset is not applied to the DAC
I have a question about xCLR pin of AD5449.
I am developing the equipment now.
The AD5449 is used for the equipment.
I have tried the equipment electrostatic test.
Then, the AD5449 doesn't operate.
Maybe, I think it to be a latch-up.
I am wanting to know if the outputs of the AD5449 DAC can be used as a differential output, thus connecting the outputs to a differential amplifier to produce a non-inverting output. Also, is there any resources available on designing the output of the…
I am wanting to use the AD5449 in my design but have a couple questions.
In our application the DA-converter AD5449 is interfaced with the SPI controller of the i.MX31 processor.
At initialization, the DAC is set up to: full SDO driver, standalone mode, CLR to zero scale, falling active clock edge.
At serial data…
AD5449 is compatible with SPI, QSPI, MICROWIRE, and most DSP interface standards, and since the maximum clock frequency is within AD5449's specs, so it should be compatible with you MCU.
Analog Devices has its own portfolio of ARM Cortex…
I want to use AD5449 in my design. The REF pin must be provided the external reference input, while the input resistance of REF pin is 11K ohm. The datasheet suggest to use ADR*** to generate the reference input, like ADR06(output current is 10mA…
