  • AD7634 Pin capacitance

    Hi everyone,

    On page 20 from AD7634 datasheet it's stated that "during the acquisition phase for ac signals, the impedance of the analog inputs IN+ and IN-, can be modeled as a parallel combination of Capacitor Cpin and the network formed by the…

  • >Unclearence regarding some Pins of AD7634


    in my project I am using the AD7634 as AD-Converter. The AD7634 is configured in 18bit Warp Mode, parallel interface, +10/-10V input signal.

    I want to control the AD7634 with the µC AT32UC3A Atmel Device.

    There are four pins from the AD7634…

  • [AD7634] Voltage level and reference for PDREF/PDBUF pins at high state


    In an A/D board under development, I'm using separate ground planes for analog (AGND) and digital (DGND = OGND) references, which can be connected together using a solder jumper or back-to-back schottky diodes underneath the A/D converter, as…

  • RE: EVAL-AD7634 - Stand-alone mode

    Hi Alan,

    Yes it is on serial mode. I tried to run it stand alone in bipolar, serial mode with hardware configuration.

    And this what I found:

    The AD7634 should work in 4 ranges, 2 unibipolar and 2 bipolar ranges. This should be configured with pin…

  • RE: Need help with the power supply for AD7634


    I just stumbled onto your ADIsimPower Excel issue comment.

    We may have fixed the issue already but in some instances the language setting of your operating system (not Excel) affects how Excel interprets commas and periods ("," or ".")…

  • EVAL-AD7634 - External serial clock


    I recently acquired an EVAL-AD7634 board and wish to operate it as stand-alone (serial slave mode), with a TI DSP TMS320F28335 as serial master. I would like to know if it's possible to provide the serial clock from the DSP to the ADC through…

  • Problems using the single-to-differential driver for ADC AD7634


    I'm using the EVAL-AD7634 development kit, which input stage consists of two buffers using low noise AD8021 op amps. My signal is single-ended, so I would like to implement the proposed Single-To-Differential (S2D) driver from the datasheet of…
