STM32 connected with AD7676 for SPI。 this my SCH。 this is my code，read data is next picture。 I don't know why like this。AD7676 have driver code example？ Thank you。
We have a telemetry deck that uses AD8021s as a single-ended to differential driver for an AD7676 PulSAR ADC as documented in the AD7676 data sheet. We want to make sure that when using +/12V supplies for the AD8021s, their inherent current limiting is…
In EE248 and in the attached SW it says that "the SPORT must be configured initially for a serial word length of 15 bits". After reading two words from AD7676 the word length is then modified on-the-fly to 16 bits.
There's not given any explanation…

Hi,Sorry for the delayed response.We suggest you to refer the EE-248 application note,which is for explains how to interface AD7676 ADCs in master serial mode (internal discontinuous clock) to ADSP-21365 SHARC® processors.
Application note: www.analog…
It would be hard to emulate SPI using Flag pins as you need to maintain timing relationship between clock and the MISO ,MOSI. You will need to toggle the flag pins everytime the Clock and data needs a state change. This becomes cumbersome. You could…
Hi all -
We are using two AD7656 6-channel 18-bit converters on a new product. We have an unexplained observation on the power supply of the prototype boards. Here's an overview:
AD7656 power supplies (all voltages nominal)
VDD = +15
VSS = …
PLease see attached list of the ADIs some of the latest differential ADCs with less tahn 2 LSB INL error. I have short listed this ADCs for DAQ systems application. I have included in the column on the file the throughput rate and full power…
