What is value resistor feedback DAC AD7538KR? It is needed for calculating current op amp DAC.
The feedback resistor is 6 kOhm typical.
May I know what is the application for AD7538? May I also know your requirements? If suitable, we have newer MDACs which may be used for your application.
Hello. DACes use for simultaneous generation 3 sinusoid. Fsin =50-200Hz. Number point on period 540. Um = 5-10B.
Could you describe how a generated 3 sinusoid would look like? What do you mean by Um= 5-10B?
Maybe you can have a look at AD5556, a 14-Bit MDAC with parallel interface.
AD5556 is fited because do not have signal chip select.
If you use 2 or more DACs, you may do one of the following:
1) Use 2 or more AD5556, but with separate /WR lines connected to each of the DAC.
2) Choose a DAC with multiple channels depending on your need, how many channels do you need?
Hi. Without signal chip select in microcontroller don't grabed pins (use 4 DACes ) and scheme is asserted manager i don't use AD5556. For future design i have in mind AD5556.
