Part Number: ADS8557 Hi Team,
A customer found a failure where all the readings received from the ADC are excessively noisy when it is expected to be a straight line at 0V.
The failure is suspected to have occurred either by a previous power shutdown…

Part Number: ADS8557 Hi,
A customer I am supporting has an urgent query for ADS8557IPM/R.
The absolute maximum rating for this part is -18V (HVSS to GND).
Their questions are:
In some of the applications the supply can reach to -19V. Does the component…
Part Number: ADS8557 After A/D conversion (BUSY = L), I read datas by Parallel Read Access (Figure 3 on SBAS404D –OCTOBER 2006–REVISED FEBRUARY 2016). I turn CONVST_x to L after BUSY=L. CONVST_x is L to next data conversion.
CS is activated for…
Part Number: ADS8557 Hi,
It is written that "when HVDD is supplied before AVDD, the internal ESD structure conducts, increasing IHVDD beyond the specified value. " on the datasheet.
If the current doesn't flow through internal ESD, should we…
Part Number: ADS8557 Hello,
My customer is designing their product with multiple ADS8557s. There is a layout recommendation in Figure 47 of The ADS8557 datasheet(SBAS404D). From this recommendation, digital GND and analog DNG and connected at one point…
Part Number: ADS8557 Team,
Question from my customer:
We have a query on what to do with the “BUSY” signal. Our intention is to start the “ConvStart” for all the A/D devices at the same time (as shown in Figure 38 of the datasheet).…
