• 使用LTC6804-2监视电池电压时,是否会出现某时刻电压采集不到

    Dear

           在使用LTC6804-2的是否会出现某时刻电压采集不到,然后寄存器显示一个XXXX的数值,这个XXXX的数值和不接电池读取的数值相同,是否会出现这个情况一般怎么处理,目前处理方法是判断一下采样值是否为有效值.

  • LTC6804-2 not responding to RDSTATA command. No data is returned. While RDSTATB is working without any issue?

    I am using LTC6804-2 in one of our products. The MCU is connected to the LTC6804 directly through SPI (ISOMD tied to V-). I have ported the sample Linduino code on Analog.com website to my application written in C, and made appropriate changes to make…

  • RE: LTC6804 异常的GPIO1读数

    GPIO1 can be affected by MUX shoot through glitches. The best workaround is to do a dummy conversion of just GPIO1 (don't bother with the read and it can be the fast filter mode), then do the GPIO conversions. Note that with un-buffered 100k sensors there…

  • LTC6804芯片SPI唤醒的问题

    你好,我想咨询下LTC6804芯片SPI唤醒的问题,初步打算采用4线SPI(ISOMODE=V-)。VREG的输入由LT3990芯片提供,芯片的EN/VVLO通过DRIVE驱动 实现LTC6804低功耗。
    1,在手册 POWER CUMNSUMPTION 那个章节 里边写了ISO SPI接口供电是由 VREG提供的,,那四线SPI实现唤醒 他的供电是否与VREG有关系,即VREG为0是否可以唤醒四线spi电路 进而唤醒CORE电路?如果采用ISOMODE=VREG模式,在VREG=0即ISO SPI未供电的情况下…

  • Pluto - 2 Rx and 2 Tx using MATLAB

    Hi,

    I would like to setup the SDR Pluto to operate in 2 Tx and 2 Rx mode.

    I have followed the steps in the following video : https://www.youtube.com/watch?v=ph0Kv4SgSuI

    However, I am unsure how to setup and control the 2nd transmitter or receiver. 

  • RE: ADA4940-2, issue on creating 2 differential signals around 0V

    Hi, 

    With a bit late, thanks for this suggestion.

    By applying -0.2V to R3, this circuits can convert 0 to 0.4V to a balanced -0.2 to 0.2V .

    It has been checked on the eval board.
