• RE: AD 7193, Noise Count Histogram

    Hello!
    in the meanwhile I changed my setup to better understand whats going on in my circuit.

    I disconnected the Load cell to check if my ADC without loadcell is doing well.
    I would like to get anywhere close this histogram:

    My values (with Averaging:1…

  • RE: ADC7767的数据采集问题

    AD的基准源是ADR441,有10mA的驱动能力,大电容为100uF的钽电容滤波。基准源的信号非常稳定。

    现在惟一的原因我认为是电源地干扰造成的,一时没有办法去除。地已经分割了,且是单点连接到大地上。模拟和数字的地是隔开的。

  • RE: AD717x, external C is required when Internal REF is enable

    Hi Akihiko,

    Yes you are correct.

    With REFBUF enabled, the buffers provide the benefit of giving the user high input impedance and allow high impedance external sources to be directly connected to the reference inputs. But when using external references…

  • ADR280 .1 - 10hz voltage noise

    I want to use a 1.2 volt precision reference for the midpoint in a single ended instrumentation amp.

    On analog.com website parametric search, a voltage noise value of 2.2 uV p-p is listed for the ADR280.

    Other parts such as the ADR441 list a voltage…

  • RE: ADuC847 Reference input range vs. ADC Range

    Bill,

    The test setup used to generate the ADC noise tables in the datasheet would have applied 0V to the ADC inputs - usually applied by shorting the external inputs at the pin. For example, AIN1-AIN2 would have been selected and the pins on the part…

  • AD780 Noise ?

    Hi,

    I am having trouble verifying the noise level in the AD780.  I have an AD780BRZ mounted to a prototype PCB with 1uF ceramic input cap, 0.01uF ceramic cap on the TEMP output and an 10 uF ceramic output cap.  I am using an HP Dynamic Signal Analyzer…

  • ADUC848: Converting a small bipolar signal.

    I have external reference 2,5V, ADR441, and I need to measure voltages in the
    range of +-80mV. Is it possible to do if the signal from my source is going to
    AIN1 and  AINCOM or does it need go to AIN1 and AIN2?
