Hi Tex,
What is the frequency of DRDY in the attached image? I assume it is 200Hz? In addition, all IO signals should be at the level of IOVDD, or 3.3V. Is DRDY 3.3V?
Also, please provide a scope capture of DRDY and SCLK to ensure the timing between these…
Part Number: ADS1278-SP Other Parts Discussed in Thread: ADCPRO We are planning to perform prompt dose rate tests on TI's ADC part number ADS1278-SP. If we purchase the ADS1278EVM-CVAL kit and download ADCPro from your web site, can I use them to collect…
Part Number: ADS1278-SP Other Parts Discussed in Thread: ADS1278 Can you confirm that all ADC digital input and output pins have ESD protection diode to both Ground and IOVDD? The datasheet says max 10mA on INPUT, so what is the current limit on the ESD…
Part Number: ADS1278-SP Other Parts Discussed in Thread: ADS1278-EP Hi team,
Is internal HW design in ADS1278-SP same with the one in ADS1278-EP?
Best regards,

Part Number: ADS1278-SP Does Texas Instruments allow to perform Precap inspection on part ADS1278MHFQ-MLS at their manufacturing premises?
Thanks in advance for your feedback.
Best regards,

Part Number: ADS1278 Hi,
My customers would like to use ADS1278 pairing with F280039 DSP to read the data transferred from ADC. They prefer to use SPI protocol along with the discrete data output mode for DOUT.
Their question is that since the SPI protocol…
Part Number: ADS1278-SP The datasheet for this part recommends a power up sequence of DVDD-> IOVDD-> AVDDD.... Would it damage the device or compromise reliability (Over a long life) in any way if this sequence was ignored and was powered up AVDD-> DVDD…
Hi Aravind,
What board are we talking about? The ADS1278EVM-PDK board? If using the EVM, the board has a PLL that can be adjusted from the GUI.

Hello Venugopal,
There is a high probability that the part could be damaged due to a fast rising voltage step on one of the 2 ground planes, causing a fast rising current pulse, such as an ESD strike or some other kind of voltage transient. The DC resistance…
