  • AFE5801: The MSB and LSB question for AFE5801

    Resolved
    Part Number: AFE5801 Hi team, Q1: The customer would like to get MSB is output first or LSB is output first in default mode for AFE5801. Q2: If the customer needs to output MSB data format, how to control? If the customer needs to output LSB data…

  • AFE5801： Questions about the input clock of AFE5801

    Part Number: AFE5801 I don't understand the meaning of "The common-mode voltage of the clock source should match one of the clock inputs of the AFE5801 (VCM) which is set internally using 5kΩ resistors, as shown in Figure 39." in application notes of…

  • AFE5801: AFE5801 Low Frequency Noise Suppression Mode

    Part Number: AFE5801 I'm wondering how the Low Frequency Noise Suppression Mode is working. Might it be a chopper amplifier configuration of the first amplifiers (left most buffers in figure 34 in the datasheet)? Thanks in advance.

  • AFE5801: When ADC sample rate is greater than SPI clock speed.

    Resolved
    Part Number: AFE5801 Other Parts Discussed in Thread: AFE5828 Hello, I got one question when I was reading AFE5801 datasheet: I noticed the maximum speed of SPI clock is 20MHz, and each ADC can reach 65MSPS sample rate. In case I would like to change…

  • RE: AFE5801: Digital Gain on the AFE5801

    Hi Praveen, Thank you for your detailed response. For clarification on what "digital gain" is exactly, I have the following questions: 1) I assume that a "digital gain" of 2 is not simply a bit shift to the left (multiplication by 2). In such…
