• Daisy-chain AD7944 and AD7942

    Hi Forum,

    is it possible to daisy-chain two different members of the AD794* ADC family?

    I would like to use an AD7944 and an AD7942 and daisy-chain both devices to a single SPI bus, similar to Figure 36 in the AD7944 datasheet: AD7944.pdf

    And if this…

  • AD7944 only toggles 4 bit at output

    Hi,

    I'm using 2 14-bit AD7944 ADCs on a imaging prototype board, one of them works perfectly, but the second one only toggles the 4 MSB regardless of the input, and the rest are either all 1s or all 0s - I've double checked the CNV control signal and…

  • RE: ADC selection for single-ended source

    Hi Usaghi,

         There is an ADI that I also wanted to suggest the 14-bit AD7944 and AD7357

    The AD7944 is pseudo differential analog input voltage range from 0V to Vref, Vref upto 5V while the AD7357 is a dual 14-bit differential ADC, which allows simultaneous…

  • Interfacing the BF-592 to SRAM or DRAM via PPI

    Would it be possible to interface the BF592 to an SRAM via PPI to serve as a frame buffer.  The system description consistes of:  Analog sensor -> AD7944 A/D (2 MSPS @14 bit) -> processor via SPI.  The goal is to capture 2 MBytes of data from the sensor…

  • RE: Queries on CN-0105: drive ckt for AD7626

    Hi Rajesh,

    I co-wrote the CN-0105, I'd like to make a few additional comments here. As for the ADA4899 vs.ADA4932, as Neil mentioned the ADA4932 provides better high frequency performance. The ADA4899 does offer better distortion performance at lower…

  • RE: ADC used for single-pulse conversion

    Hi Postino,

    Here are some list of ADC that could be suitable for your application. You may also wanted to check the ADI website and do a parametric search and put in parameters on the ADC that you wanted to search. Please refer to the link below.
