• AD7403 VDD2 vs AD7403-ep

    Hi,

    I was hoping to use and AD7403-ep (or the V62/16625 equivalent), but I noticed something odd:

    For the AD7403, the specified range for VDD2 is 3V to 5.5V, while on the AD7403-ep it is limited to 4.5V to 5.5V.

    Is there a reason for this?  All my I/O…

  • AD7403: CSA rating

    Question:

    The VDE Viorm = 1250 Vpeak reinforced isolation rating for the AD7403 is much higher than the CSA reinforced rating of 415 Vrms (586 Vpeak). Why is this the case?

    Answer:

    Different regulatory bodies such as VDE and CSA have different criteria…

  • Why has the power consumption of the AD7403 increased when compared to the AD7401A? 17mA typical at 20MHz and Vdd1 = 5.5V for the AD7401A and 42mA typical for the same conditions for the AD7403

    Question:

    Why has the power consumption of the AD7403 increased when compared to the AD7401A? 17mA typical at 20MHz and Vdd1 = 5.5V for the AD7401A and 42mA typical for the same conditions for the AD7403

    Answer:

    There are a few factors to consider that…

  • What is the difference between performance range and full scale range of the AD7403?

    The performance specifications listed in the data sheet are for a +/-250mV input signal. If this input signal range is exceeded the AD7403 will continue to operate but the specifications are not guaranteed. So to maintain accuracy it is recommended to…

  • AD7403: clock loss and restart

    Does AD7403(-EP) supports a temporary loss of MCLKIN without power loss ?

    When the clock restarts without power cycle, does the IC behave nominally (as if it has just been powered on) ?

  • AD7403测电压问题

    16位隔离式Σ-Δ型调制器AD7403,求当输入单极性(测电压,正值波动,频率200Hz)信号的典型电路,需要RC滤波吗?急求!!!

  • Decimation with AD7403

    If I average  a large number, say 100,000 values from the AD7403 can I get better than the 14 ENOBs ?

    Is there a limit?
