• AD1955: Independency of the channels

    I have a question about AD1955 Stereo D/A converters. I am wondering that if
    we are able to use the left and right channels of this DAC as if they are
    indepent channels. That is, can we say that we have a single chip having two
    independent DACs…

  • AD1955 gain error in External Digital Filter mode

    Hello,

    I want to use the AD1955 DAC in External Filter mode. But when I use this mode I have gain factor of about 1.12 higher compared to the DAC used in PCM mode.
    In PCM mode, I have a full scale of  8.64mA as shown in the datasheet.

  • ad1955 输出固定频率失真

    我使用I2s给ad1955发送1k正弦信号的数据,会出现下图的信号失真,我给的I2S信号是完整的,没有失真。

    寄存器配置是I2S,8k,16bit ,24.576MHz,MCLK=512fs。可以调节音量和静音,SPI通讯正常。

    电路基本上是按datasheet设计,两层板。

    换了好几个芯片都是这样的。

    如有回复,万分感谢。

  • No sound from AD1955 when set to 192

    Using the AD1955, I have set the 00 control register bit 9 to a 1.  All other bits are 0 in both registers.  This should set the D/A to INT2X mode/192 correct?

    I get no output when feeding the D/A with  (44.1- 256fs),  (96 - 256fs)  and  (192 - 128fs).

    I do…
