Part Number: ADS7957 Other Parts Discussed in Thread: TEST , STRIKE Hi Team,
My customer found after applied 15kV air discharge and 5kV contact discharge ESD test, the output is FFC, even with input shorted to ground.
They tried two ways below, both can…
Thanks for the suggestion.
Actually, I managed to make it work by changing the SPI clock to 1Mhz (very slow, but at least it is working).
This suggests that maybe there is some hardware issue... I will have to investigate it on my own.
Thanks for the…
Part Number: ADS7957 Hello,
my target is to set the ADS7957 IOs per SPI command. Problem: I can see the set output values neither on the SDO data (if this mode is selected), nor on the outputs.
I can confirm that the communication itself is working properly…
Part Number: ADS7957-Q1 Other Parts Discussed in Thread: ADS7957 Hi,
I would like to ask you some questions related reset of ADS7957-Q1 as below.
Q1) Reset
I suppose there is no "reset" pin with ADS7957.
Could you tell me how to reset this device…
Part Number: ADS7957
I'm trying to solve a problem that has an obvious answer but no explicit information in the datasheet. The VQFN package for this part presumably has an underside pad which is presumably connected to ground, but the datasheet doesn…
Part Number: ADS7957-Q1 Hi,
Let me ask you some questions about Serial I/F timing of ADS7957-Q1 as below.
Q) 7.8 Timing Requirements, page 11
There is a table about I/F timing on 11 page, "7.8 Timing Requirements".
This timing specification…
Part Number: ADS7957-Q1 Hi,
Let me confirm following items about the behavior of ADS7957-Q1.
1) "SDO output data" after power-on rest
I understood that,
After power-on rest, the device is initialized to "manual mode" and device is ready to wait…
Part Number: ADS7957-Q1 Hi,
I would like to ask you some basic questions about the relation between input source impedance and throughput rate as below.
Q1) Figure 58, datasheet page 40
There is a description "Note A" and there describes that "Rsource…
