Category: Datasheet/Specs
Product Number: AD5668
Hello,
We decided to use AD5668 for our new device /product .
We purchase the evalboard EVAL-AD5668SD_Z rev C.
There is no digital interface so we wanted to implement it directly by driving the converter with our microcontroller board.
As we intend to use the internal reference we started by sending the spi command 0x08 as in the attached snapshot. first Without LDAC
Then with LDAC , we tried also 0x09.. but we dont see the reference voltage on pin 8 of the chip or on TP1. Neither the cha voltage to change.
WIll be grateful for Any help!!
