AD5721R fits our application concerning its specifications, 0-10V, +/-10V output etc. but we require the input data rate is higher because the 10 MHz sine wave signal is converted by ADC and after software processing it is convered to analog signal that…
I want to used AD5721R/AD5761R to produce arbitrary waveform (frequency=100kHz , amplitude=0~10V) to drive a device. But , How to calculate this condition (frequency=100kHz , amplitude=0~10V) through settling time? Does AD5721R/AD5761R…
I'm hoping that I can just keep posting questions in here as I get them and people with experience with this chip or similar and circuit design can chime in and help.
So here's the goal. I will be pairing this chip with a Teensy LC in a vehicle…
I forgot to ask, can you also provide oscilloscope shots of the supplies (DVcc, VDD, VSS) when this happens?
I would like to make clear about EVAL schematic of AD5761R/AD5721R.
According to UG-751
Page 7, pin#9 is connected to GND with CAP.
A 12-bit part, AD5721R, is the closest part I can recommend. Is your controller capable of sending 24-bit SPI frame? For which application are you going to use the part?
The transfer function is:
#AD5721R range setup
Vout can not reach +/- 10V if VDD=+5.5V and VSS=-5.5V. Vout can only reach +/-4.5V due to the 1V drop. But how shall I program RA to get +/-4.5V Vout?
The documentation states that the register RA is…
Q1. What external devices does the part require to operate as spec’d in the datasheet?
A1. The AD5761R/AD5721R are 16-/12-bit Voltage output DAC which integrate a 2.5V 2ppm/˚C typical internal reference as well as reference and output buffers. The…
