Hi Ryu,
Sorry about the delay, there is no specific power sequence for the ADS8330. You can tell by looking at the ABS MAX table on page 2. There is no entry comparing +VA to +VBD, so either can come up first. Restrictions are placed on the ground potential…
Part Number: ADS8330 I have been trying unsuccessfully to configure and verify the configuration register on the ADS8330. From the data sheet and other documents it appears the SPI should be CPOL = 0, CPHA = 1. When I try and write 0x5FD to the configuration…
Part Number: ADS8330 I'm curious what the exact purpose of +VA is, like, what is it powering?
Does it need to be a low ripple source? If yes, can I just power it from my voltage reference or is that a stupid thing to do?
The voltage reference I'm using…

Part Number: ADS8330 Hi Team,
The electrical characteristics table at page 4 of the datasheet shows the voltage reference input of ADS8330 has a resistance of 40k ohm. Our customer would like to know the maximum current consumption of VREF pin including…
Part Number: ADS8330 Other Parts Discussed in Thread: SN74LVC2T45 I use FPGA to control the ADS8330 with the mannual mode, when I power off the ADS8330 and power on again, the chip is frozen, but the FPGA is always powered on. Please help me, thank you…

Dear Sir/Mam,
i have interfaced ADS8330 to tms320c5505..i am using both the channels..with auto mode with SPI clk 4MHz. following is the code to get the samples.inputs are 50Hz,1V sinewave…

Part Number: ADS8330 We are getting data out of this chip, but there seems to be issues with the data. Mostly, the last three bits coming out are nearly all 100, effectively reducing the 16-bit resolution to 13-bit. Before we go to the trouble of reconfiguring…
Hello Jose,
I have the same question about the power management of ADS8330 .
However I would like to shut down VA before VBD.
Is it necessary to execute the same recommendation for the power up phase?
Thanks in advance for your help.
