• LTC2471 Noise

    The data sheet states the input referred noise at 3uV rms. Is this at 208SPS?

    At 833SPS would this be 3uV * sqrt(833/208)?

    Is there an approximate figure available for the 0.1 to 10Hz reference noise level woith the recommended 0.1uF on REFOUT?

  • LTC2471 I2C No Ack

    The SCL and SDA are connected to PIC16F1947's I2C interface.They all working at 5V.

    And the Wave:

    The SDA is HIGH at 9th clock, but it should be LOW. It means that the LTC2471 didn't send an ACK. The A0 was connected to GND, so the address is 0010100…

  • LTC2471的I2C接口没有ACK应答。

    LTC2471的接口部分如图所示:

    其中SCL和SDA直接与PIC16F1947单片机的I2C接口的SCL和SDA相连。VDD电压5V。

    用示波器测量SDA和SCL的波形如下:

    可以看到不管是读还是写,最后一位本应由LTC2471将SDA拉低的电平一直为高电平,即无ACK应答。请问有可能是什么地方出了问题?

  • AD-FMCLIDAR1-EBZ on Altera Arria 10 Soc Dev Kit

    Hi,

    I am testing the AD-FMCLIDAR1-EBZ on Altera Arria 10 Soc Dev Kit by using the latest Linux image (2019_R1-2020_02_04.img).

    The DK was able to boot up and detect the chips on the DAQ board (AD9094 and AD9528). However it is failed to detect the chips…

    Hi, I updated the SD boot image “23 February 2021 release candidate (2019_R2)” through Etcher.

    But Etcher's check result at the end of write stage was fail.and the 32GB sd card's capacity was changed to less than 1GB.

    The boot log was…
