Hi,All
Please let me ask you a question about ADS7830 because I was asked it by my customer.
When they read a sampling value without wait time as following upper diagram,
read value is always higher than true value by 2 or 3 LSB.
But when they read a sampling value with more than 25usec as following lower diagram,
read value is correct value.
Is there a rule about wait time?
According to a datasheet P3,conversion time is written 5usec so they tried it ,but the results were wrong.
It seems that clock frequency to SCL is lower,read value is closer to correct value.
Is there a relation between read value and clock frequency?
Best regards.
Taichi.
