• AD7770

    Hello!

         I have question regarding the analog channels of the AD7770: are the analog channels isolated in AD7770? Can they be coupled directly with signals coming from plcs? Isolation amplifiers required for AD7770 if necessary?

    Thank you!

  • AD7779 and AD7770

    Hello,

    I have a question about a differencis of digital flter between AD7770 and AD7779.
    Attached file is the rms noise and resolution performance table from the datasheet.
    AD7779 and AD7770 have same combination of ODR and Decimation Rate excluding 32kSPS…

  • AD7770 Evaluation Board: No DRDY pulse after RESET pulse.

    I'm using the AD7770 Eval Board. The Main Supply of the board is from the 9V external Wall Adapter and I want to get ADC data to Altera FPGA board  through J1 header ( SPI mode)

    However, after the power up the DRDY signal is always at LOW state. I…

  • EVAL-AD7770FMCZ - AVSSX supply

    Hello,

    I use the AD7770 evaluation kit and supply it with an external +9V power supply. All bridges are in the basic position, except the MAIN SUPPLY in position B and SL1 in position B.

    When I measure the power supply voltages of the AD7770, I observe…

  • RE: Why is AD7770 mode 3 pin (Alert SPI) always high? If we disconnect the ADC from the MCU, then we disconnect the ADC from power and reconnect it to power (we are assuming that resetting power would reset all the registers), and then probe the Mode...

  • AD7770 maximum range

    Hello,

    I'm using the Eval Board of AD7770.

    The maximum amplitude I can measure between AIx+ and AIx- is +/- 1.65V (dual supply operation)

    According to the AD7770 datasheet, he noted that the maximum amplitude is +/- 2.5V (according to table 11 of…

  • Did the EVAL-SDP-CB1Z could be replaced by the EVAL-SDP-CH1Z ?

    Hi,

    I would like to evaluate three ADC. THE AD7770, AD7768 and the AD7124.

    The evaluation boards of the AD7770(EVAL-AD7770FMCZ) and AD7768(EVAL-AD7768FMCZ) need the Demonstration platform "EVAL-SDP-CH1Z" whereas the evaluation board of the AD7124(EVAL…
