I would recommend that you look at the AD1938; this is the full codec version of the AD1934. This codec, as well as the AD1934 DAC, work well in the 32 kHz rate environment, using the PLL at 256 x Fs clock rate.
I am want to use AD1934 to design my audio system , but I not found any reference design or EVB information on website. Could you help me to use AD1934 ?
"I2C" is mentioned in function block diagram of AD1934 product page.
Why not to remove?
Recently I used the BF518 to control two AD1934 to play audio through TDM mode.Last ad1934s can play in 8 channels. Could you give me some examples? Like this picture.
I use the BF518 to control two ad1934 ,and ad1934 in Single-Line DAC TDM Daisy-Chain Mode.LIke the next picture.
The next is my register configuation ,is right?
PLL_Control_1 -- 0x00,
DAC_Control_0 -- 0x40, ***???
Dear support team,
I want to know total delay of AD1934.
In datasheet, Group delay of DAC interporation filter is 42us@192kHz.
Is it total delay?
If no, please teach me total delay(Analog input to output register, not include shift time of I2S)
Recently, I use the BF518F to control the AD1934. I know that the AD1934's SPI port allows a microcontroller to adjust volume and many other parameters. AD1934's SPI format is similar to the Motorola SPI format except the input data-word is 24…
I'm interfacing the AD1934 DAC to an MCU's SPI interface. I have connected a 12.288MHz external clock signal to the MCLKI pin and left MCLKO pin as open.
Following are the AD1934's register configuration.
DAC Control 1 --> 0x60
I still have a question about this SPI timing.
You have already given me answers for the tCOE, tCOH, and tCOT.
I am fine with your answer. Thank you so much.
tCOH and tCOT
I am thinking a case where the "Table 7 on the AD1934 data…
Thanks your reply again.
Question1: "The position of the MSB is set by bits [5:3] in the DAC Control 0 Register 0x02." ?! Is this you? If DSP transmit 16bits data such as 0x9306(1001_0011_0000_0110) and [5:3] are seclected 000. AD1934 will…
