• AD7676 Read data error

    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。

  • AD7676 with AD8021 drivers

    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…

  • AD7676 interface to ADSP-2136x

    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…

  • RE: AD7671 interfacing with ADSP21369 using SPI protocol for SERIAL mode

    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.

  • RE: SHARC(21366)  SPI Emulation using Flag pins

    Hi,

    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…

  • AD7656 power supply anomaly

    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 = …

    Hi Jebas,

    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…

  • RE: 基于SHARC 处理器的系统设计与调试技巧

    软件程序及技巧(这部分重点推荐了 SHARC 处理器的一些外设单元的程序)

    PCG(外设时钟发生器)编程

    本部分主要讨论使用 PCG(精确时钟发生器)为 SHARC SPORT 提供时钟的注意事项。

    • 使用 PCG 产生的信号为 I 2 S 模式的 SPORT 提供 FS 和 SCLK 信号时,需要配置 PCG 的延迟寄存 器,使信号时序与 I 2 S 协议时序一致。LRCLK 信号必须由串行时钟的下降沿驱动。 „
    • 使用 PCG 为 TDM 模式的 SPORT 提供信号时,要求帧同步信号仅在一个串行…
