Part Number: ADS8557 Tool/software: Hello,
We are analyzing possible error states of our design. We are using ADS8557 ADC in HW mode, with internal reference and Range +/-4*VREF.
Normally we have a +/-12V HV voltage; but in one possible error situation…
Part Number: ADS8557 Tool/software: Hi team,
As one of the EMC tests, the output of the ADS8557 on the board is locked in place when static electricity is applied to the metal enclosure that surrounds the board externally. Are there any possible causes…
Part Number: ADS8557 Hello,
Question related to ADS8557IPM: If we have no HVDD/HVSS voltages (due to a failure in a DC/DC converter for example). Would the digital part still work? I mean, if we have HVDD=HVSS=0V; and AVDD=BVDD=5V, would BUSY signal…
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…
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 each…
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 begin…
