使用AD5665R时，使用FPGA逻辑模拟I2C总线配置4个电压输出，如果输出端不接负载上电I2C单次配置便可以正常输出，但是接上负载之后上电就会发现配置输出电压升高一点便又回落到0(负载不大，几十毫安电流)，偶尔出现配置成功。尝试I2C循环配置，接负载每次上电输出电压都小于程序设置电压，且每次不尽相同。几块板子现象一致，不知是什么问题…
Please tell me what is USB driver of "EVAL-AD5665R" as win8.1 64 bit?
Is this same as CY7C68013A driver?
I don't find any USB driver in Cypress web-site, would ADI be available to provide the AD5665R win8.1 64bit USB-DRIVER?
Thanks, Keiichi…
Hi, the AD5544 do not operate in single supply operation, there must be an errata in the documentation for this part. Could you tell us where did you get this information from in order to edit it and avoid future misunderstandings?
The single supply…
nanoDACs are a portfolio of products which combine small package, low power and low cost digital to analog conversion.
nanoDACs are monotonic DACs which can be powered off a single 3V or 5V supply and are available in the industries smallest packages…
It must be stressed that depending on the application performance requirements, all nanoDACs can be used in both open and closed loop systems.
In an open loop application the DAC drives the load (a valve or an actuator, for example) directly while in…
The AD5664R has two on-chip reference options available, 1.25V and 2.5V. What is the recommended supply voltage in each case?
