I want to know AD5627R/47R/67R internal 1.25V and 2.5V reference voltage accuracy is how much?
I have a Problem with the AD5627R. (in MSOP Package)
The Output is not Rising higher than 0,3V (@ 0x0FFF), When I change the Input the Output follows so I can see it works somehow.
I am using the internal reference ( I have 2,42V on the reference…
we have a problem using the ad5627r that we cannot get to output voltage other than 0V.
- Supply and comms are OK, because we successfully flip Vref on/off via I2C.
- No matter what value we write to DAC, the outputs remain low.
//AD5627//DAC #define AD5627_VOUTA 0x00 //A A2 A1 A0(000) #define AD5627_VOUTB 0x01 //B A2 A1 A0(001)#define AD5627_BOTH 0x07 //AÇÒB A2 A1 A0(111)

Quoted below is a conversation cut and pasted from a Facebook Messenger thread between ADI and a customer who is trying to identify parts based on the package markings. Can we help?? Happy to refer him to a discussion forum if that is easier.
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…
I am unsure how to connect the LDAC (pin 4) and CLR (pin 5) pins. I want to have an immediate output without buffering and assume that I can tie LDAC low and leave CLR unconnected. Am I correct in connecting the DAC in this manner?
The AD5664R has two on-chip reference options available, 1.25V and 2.5V. What is the recommended supply voltage in each case?
