we are using an AD7357 and an AD8132 to drive the inputs of the AD7357. Trouble is, we see large voltage swings at the Vin+ and Vin- of the AD7357 which are not related to the signal we feed into the AD8132. We use pretty much the recommended…
I'm currently using the AD7357 and I was wondering if I can pull up NCS (N for not) right after the 16th falling edge of SCKL or if I should wait the 16th rising edge of SCKL as shown on the picture 31 of the datasheet?
Thanks in advanced…
I have some problems with my ad7357-eval kit. When I input an AC signal to the corresponding pins Va or Vb the signal seems to have a drift of ~0.2V. For example if the input is 0 - 0.6 AC (e.g. from AD9837) it becomes 0.2-0.6. This error is quite…
1) What is the maximum conversion time in the AD7357?
2) Do I can sampling at 10 Hz?
in power mode , it was mentioned that in first time a few cycle has to be elapsed then only conversion start.
1.But i my case i am using cs is low for 0.5usec, when cs is low sclk( each cycle frequequency 40Mhz) pulse start ,so conversion will start…
Hi. I have a problem with the AD7357 ADC, meaning that each time I ask the device to make a conversion it gives back a different conversion , although it is the same tension at the inputs. It should have returned the same value each time but it varies…
the question: is 36mW of power reported on the datasheet the total power consumption,
I mean when the two channels are converting, or for just one channel?
Our customer will use AD7357.
Its serilal interface timing describes datasheet rev.B P.18 Figure 30 .
Figure 30 says that first SLCK edge after CS_ low is falling edge.
Could you teach me if there is any problem when the first SCLK edge after…
The datasheet does not mention anything about differential input (e.g., Figure 1 on page 1). Even Table 6 does not even mention J15 or J16 (which I see on the actual board and in the schematic).
From the schematic, it seems straightforward --- to set…
