• RE: AD7134 phase matching

    Hi Christer

    your observations are correct, if we consider just the ADC's then for AD7134 the numbers arent great. But when we look at the whole signal chain these numbers are better as the mismatches induced due to the Anti-alias filter are no longer…

  • RE: AD7134 HDL

    Hi ,

    You can use the github's search tool on our hdl repository: https://github.com/analogdevicesinc/hdl

    If using Zedboard you probably want this file https://github.com/analogdevicesinc/hdl/blob/master/projects/ad7134_fmc/zed…

  • DClock min for AD7134

    How is DCLK min being calculated here? Where is the 8 coming from? When I put those numbers in I get 56.848 Mbps.

    Thank you for any clarification.

  • RE: AD7134 Data CRC calculation

    Hi,

    Sorry for the delayed response.

    You can use the CRC calculator https://leventozturk.com/engineering/crc/ 


    Here are few clarifications on the CRC calculations done:

    Polynomial: x6 + x5 + x2 + x + 1: 0x67

    Initial seed/initial value: 0x25

    Data width: 24…

  • AD7134 SPI connection

    I would like to connect multiple AD7134 devices together and control these via the SPI interface. Does the AD7134 support daisy chaining the SPI interfaces?

  • ad7134

    we are planning to use AD7134 for acquisition in our project. we are having following queries about the chip

    1. can ad7134 be integrated with ADA8282 in ac coupling mode? This doubt we got because ADA8282 doesn't have any common mode voltage at its output…

  • AD7134: FAQs

    Q1. What anti-alias filter is required for AD7134?

    The architecture of AD7134 offers excellent attenuation of out of band high frequencies providing 102 dB inherent Alias rejection which caters for most of the application requirements.

    Along with the…

  • AD7134 with ADA4254

    Hi,

    My application is to create an 8 channel, synchronously-sampled data acquisition system for signals from +-5mV to +-10V synchronised to an external 40kHz sample clock (and I'm looking at ways to increase that for various performance & spec reasons…

  • Regarding AD7134

    I am working on an acquisition system with ad7134 and ada8282 ,  using eval boards for the same.

    This system has been connected to a function generator feeding -15 dbm single tone input to the eval ada8282, the ada8282 has been programmed for 18 dbm gain…

  • AD7134 decoupling capacitors.

    Most designs using other ADCs call for decoupling at the device power pins with two capacitors, a 10uF electrolytic or tantalum cap and and a 100nF ceramic cap (to decouple HF noise).

    However, the AD7134 only mentions using the high value caps on DVDD1V8…
