• AD7795 calibration

    We are using AD7795 in a product. Factory sys cal takes place at 60mV on
    appropriate range. We now have a requirement to also add a lower range. Is
    there a way of calculating the cal register values for the lower range from the
  • ad7795 burning up

    I've had several failures in a product line using the ad7795.  The ad7795 is being used to measure the resistance of RTD temperature sensors.  In a few of our boards the ad7795 burns up.  My technician is reporting burn marks on the top of the part and…

  • Initializing the AD7795

    Hello all!

    I'm having trouble getting the AD7795 to work in a project.  Here's what I'm trying to do:

    The AD7795 will be connected to a Freescale i.MX 6 Ultralite over SPI.  The i.MX6 Ultralite is running Debian with kernel version 3.14.38…

  • AD7795 hangs periodicly

    We use the AD7795 to readout 3 resistor bridges. These are connected between
    AIN1, AIN2 and AIN3. The reference is taken from an external reference of 1V.

    We let the measurements run continiously. After an uncertain time the AD7795
    hangs and only returns…

  • AD7795 REFIN+/-

    Dear community, we inted to use AD7195 with AC excited strain gauge but in datasheet we have seen that pin REFIN+ must be in the range AVDD-AGND+1 and REFIN- in the range AGND to AVDD-1. If we use AC excitation pin REFIN+/- range from AVDD to AGND. Is…

  • AD7794/AD7795

    Hi all ;

    I would like to design a loadcell reader and pressure reader; in   our old control card we used to use AD7705 ; but now I think AD7794/95 is better ; it is six channels ;

    I confused about which one is the 24bits resolution 94 or 95?

    other question…

  • AD7795 SPI issue

    I'm having trouble communication with the AD7795 via SPI. I'm using the chip in single conversion mode.

    The AD7795 is connected to an FPGA via the SPI interface.

    The FPGA first issues a reset command by clocking out 32 1's into the DIN port…

  • AD7795 External Clock

    In single conversion mode the AD7795 powers up takes a conversion then returns to the power down mode. I presume the internal clock is stopped during power down mode.

    I want to drive the ADC with an accurate microcontroller derived 128Khz clock for better…

  • AD7795/96 Internal Offset Cal

    I am using the AD7795 in a multichannel temperature application.  The product is calibrated at the factory with a system offset and gain cal before test. The calibration values are read from the AD7795 and stored in eeprom. They are loaded on power up…

  • [AD7795] unused IOUT2


    I would like to know unused pin termination.

    When AIN5+ and AI5- use as IOUT1 and IOUT2.

    The customer needs only IOUT1 with 1mA.

    But according to data sheet IOUT2 seems cannot disable when output current is 1mA.

    Is this unused IOUT2 should…
