Is there any difference between AD5755 & AD5755-1 architecture? In the datasheet of AD5755-1, accuracy specification for voltage output is provided for both unipolar & bipolar power supply. But the same is not available in datasheet of AD5755 (only…
The CHART pin takes an AC coupled input and is summed to the DAC input. See Figure 2 of the AD5755-1 datasheet. CHART should not be tied to 0V. If CHART is tied to gnd, Iout will not work and the part may get hot as a result.
I have followed the sequence mentioned in flowchart given in datasheet to configure AD5755-1. I have configured control register and trying to read back same register but, I did not get any data on SOUT. Please send us the initializing sequence for the…
The AD5755-1 datasheet says:" The correct method to calibrate the gain/offset is to first calibrate out the gain and then calibrate the offset.".what's that meaning?I think it shoud calibrat offset first at zero. And I expecd get detail method…
I am currently working with AD5755-1 and i would like to ask if it is possible to tie Vout and Iout.
This way i would not need jumpers to sell voltage output or current.
thanks in advance.
From the datasheet the maximum value for gain register is 0xFFFF (2^16-1). According to the equation on page 41
Code = D * (M + 1) / 2^16
So for 0xFFFF the code value is D (2^16-1+1)/2^16
So any number other than 0xFFFF will make the adjusted…
I used my MCU board, which is equipped with a TI MSP430 MCU, to control the AD5755-1. I have implemented the SPI communication layer followed ADI's example driver. I think that the SPI communication layer of my code seems correct because…
I want to make ad5755-1 as a charger, 4 channels of Iout output 4~20mA at the same time, and each channel load is 500Ω to 1KΩ. Can the ad5755-1 provide such load capacity? What aspects of the design need attention?Thanks
