• ADC LTC2512-24 Driver Inquiry

    In ADC LTC2512-24 datasheet, LT6202 is recommended to be used as ADC driver. But in "Precision ADC Driver Tool - BETA", there is no option to use LT6202 in driver selection (only LT6200 available). In this ADC driver tool,  ADA4807-2 seems to…

  • LTC2512-24 SDOA has no output

    Hello,

           I have a problem using LTC2512-24.The chip's  14-bit no latency output has data output, but the 24-bit filter result has no output. In my design, RDLA,SYNC is driven low by FPGA,  MCLK=1MHz, DF=4, each conversion period has a busy signal, but…

  • Why is the LTC2512-24 output delayed?

    1. I use the LTC2512-24 digital filter to output SDOA, and the sampling data has a delay;
    2. According to the manual, use SDOB without delay output, but there is still delay in sampling data.
    Thanks Reply!

  • LTC2512-24 开发

    有谁开发过这款芯片?目前调试的现象是22位的no latency output 有输出,但24位的滤波结果没有输出。MCLK=1Msps,DF=4,每个转换周期都有busy信号,drl信号每隔85ms周期被拉高一次(与手册描述的每隔DF个转换周期拉高一次不相符),在drl信号下降沿后给scka信号,并没有数据从sdoa引脚输出。驱动时序已经按照手册要求写的,并有检查无误。

  • Why does the LTC2512-24 only work for a while?

    Hello, I applied LTC2512-24 design acquisition circuit, FPGA driver chip, DF=4, MCLK=1MHz, SDOA output, but the chip can only work for a while at a time, need to restart the power to work again, but also work for a while。

  • Why Ltc2512-24 has BUSY signal, no DRL signal

    DF=4,MCLK=1MHz。

    There is no DRL signal after working for a while, but there is always a BUSY signal.

    It works normally within 1 minute after power-on, and there is no DRL signal after 1 minute.

    Thanks Reply!!!

  • 请教下关于LTC2512-24芯片输出延时问题!!!

    各位有没有用过LTC2512-24这款ADC芯片,根据手册介绍,SDOA输出是滤波输出,有延时,后来用了无延时的SDOB输出,但是数据还有延时,请教下是啥原因啊?

    ADC驱动用的FPGA实现的,严格按照手册时序写的代码。

    感谢!!!

  • LTC2512 Timing Specification

    Hi,

    We are using LTC2512CDKD-24#PBF, with the following configuration

    down-sampling factor of 32

    the SPI clock frequency of 5.5296 MHz

    Unipolar mode

    filtered output.

    In the datasheet the ADC timing characteristics has been given for 100MHz frequency…

  • RE: LTC2512 - ADC not updating the output register in single shot read

    If you look at Figure 22 on page 25 of the LTC2512-24 data sheet you will see that a total of 35 cycles are required for full settling of the filter. This is fixed in this device and cannot be changed.

  • LTC2380-24 SNR SINAD

    Hi ADI,

    According to LTC2380-24 datasheet, SNR,SINAD dropped according to the input frequency. But the chart only shows 0 to 200KHz. Do you have more information about higher frequency?

    Thanks!

    Cheers
