你好，关于AD7992有官方驱动程序参考嘛？另外，我想问一下，启动和停止时序图上比较清楚，ACK（应答信号）从时序图上不是很清楚，请问有详细的时序图嘛？AD7992-0供电电压为5V，最小转换时间为多少？

Hi,

When AD7992 is operated in Mode 3 - Automatic cycle mode, what should be the connection for CONVSTn pin?

thanks,

Hi,

I'm using AD7992 on a custom board and its Linux driver seems to only partially work. I'm using linux kernel 4.9.4 and I've defined the device tree as follows:

 ad7992_vcc: fixedregulator0 {
    compatible = "regulator-fixed";

Hi, Here are the description of the CN0288. It shows that the signal dynamic range is 82dB, while the SNR of AD7992 is only 74dB.I think the dynamic range is not sufficient for AD7992,we should use higher resolution ADC，do you think so?

Below is the…

Hello,

I'm using AD7992 and I have VDD set to 5.0V but my MCU is at 3.3V. There is a condition where 5.0V gets turned off to save power, but the CONVSTn and ALERT/BUSY lines are pulled up to 3.3V with a pull-up resistor in order to communicate with the…

Hi

We are using both input channels of the AD7992 and its power supply is the reference. We use the command mode (mode 2), to set the ADC up and read the data back it. The I2C sequence used is as explained in the datasheet:

<7-bit address + W> ACK …

Dear community,

I am facing a problem when trying to use the AD7992. I have a Linux based Board which I am using for development of different sensor systems. The board has been extended by using a PCA9544A Multiplexer (4-Channel) to have 4 I2C-Busses…

I would like to be able to "freeze" the value in the conversion register while in Mode 2 using a signal local to the AD7992.  Will holding ^CONVST high prevent the start of conversion that would be initiated by an I2C write command (or at least…

Hi All,

We are using AD7992 analog to digital converter in our new

DWDM-PON based ONT design. The preferred mode of operation for the

converter is Mode 3 i.e. the Automatic cycle mode. Please confirm

whether the I2C clock is used for polling…

你好，最近在用AD7992,驱动是参考AD7991代码的，但是我看AD7991驱动的时候，有个delay(1000);这个代码延时大概是多长，我按照时序图写的代码不知道为什么一直读取出来的数据是FF，希望能得到官方支持。谢谢，希望尽快回复。
