Hi Ryan,
I would not recommend turning off the VDD of the AD7992 and at the same time pulling CONVST and ALERT/BUSY with 3.3V. If there is a need to save power, the AD7992 has modes of operation and to shutdown to save power when the AD7992 is not converting…
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 Mayank,
The conversion clock used in Mode 3 (Automatic cycle mode) is provided by an on chip oscillator. The conversion clock period is specified in the “Cycle timer” register. As the I2C bus should be quite during a conversion (in order to achieve…
Hi,
When AD7992 is operated in Mode 3 - Automatic cycle mode, what should be the connection for CONVSTn pin?
thanks,
Manju.
I can refer you to AD799x ADI part that also uses I2C interface. This part has ALERT feature that acts as an out of range indicator, if enabled, becomes active When conversion results violates the DATAhigh or DATAlow register values.
Please…
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";
As per last response, The AD698 linearity spec typically at 75ppm will have an 13.7 bit accuracy, the worst would be at 500ppm which is a 11 bit accuracy.
So, instead of using AD7992 which is12 bit ADC, if i use 14-bit or 16-bit ADC, what would…
Hi Kazu,
Currently ADI have the 12 bit resolution in the portfolio, the AD7992 (AD7994 -4 channels) and as mentioned the LTC2451 but the concern is the address was factory set. Is it okay for you to share particular application to be use.

这个芯片(AD9833)的名字我猜的,可忽略看,如果是这个芯片,左看右看也不知是干吗呢?
