• AD5452 vs. AD5453

    Is there any major difference besides the amount of bits loaded into these DACs? I'm currently testing a circuit that originally used the AD5452 with the AD5453 instead, and am not getting the correct output (the output range is .4-.6mV instead of 0-5…

  • The BW of AD5452

    Hi:

        I am using the AD5452 to  modulate the amplitude of 12 V p-p SINE signal and triangular wave.But it cause severe distortion when the frequency is 1MHz,triangular wave is even worse.It is described that the BW is 12MHz with the +-3.5V signal in datasheet…

  • 关于DAC芯片AD5452的带宽问题

    各位工程师你们好:

                                    最近用到AD5452这款DAC做+-6V正弦波和三角波信号的数字调幅,可是当信号到1MHz时波形就失真了,是因为带宽不够么,手册里描述基准电压+-3.5V时带宽为12M.会不会是这里的问题呢?另外DAC有没有类似运放的压摆率之类的指标呢?

    或者大家有没有类似于AD5452封装的DAC可以推荐。谢谢!

  • AD5452 50K W=0 but 64Ohm?

    Hallo, i use AD5254 50k for a simple Audio mixer. Instead of an analog Poti i set the AD5452.
    I wonder, because wenn i set the W on 0 i can hear a Little bit Audio, althoug B is set on GND.
    Now i measure a resistor of 64OHm between W and B, when set on…

  • High frequency noise at the output of a 4th order filter

    On a board, we have several identical channels of an analog signal generation chain. A single channel consists of an AD5452, followed by ADA4807-4. We use all 4 opamps on the ADA4807 package to construct a 4th order filter at a cutoff between 150-200khz…

  • RE: AD539

    Hi js

    Thanks for your response.

    We could not find any VGAs meeting our requirements. These are:

    -          Bandwidth 10kHz -> 10MHz

    -          Control-input must be analog (or at least 8bits if digital)

    -          We want to have a dynamic range of the signal to 40dB (x100…
