Part Number: ADS7950 Other Parts Discussed in Thread: TLV1570 , TMS320C6742 , hi Expert,
My existing project design is using McBSP to interface between TLV1570 and TI DSP TMS320C6742 as following
But TLV1570 is entering LTB status now. So I am planning…
Part Number: ADS7950 What is the REFP pin max current draw? Have an application with one source driving multiple ADC chips. Would be nice the info is in datasheet.
Zhiyao,
If you applied a current less than 10mA through an ESD diode and it read 1.57V it is damaged. I think that the diode test on most digital multimeters would use a current less than 10mA, so your diode is likely damaged. If you applied a current…
Part Number: ADS7950 Hi Team,
I want to use the ADS7950 in a battery powered device and wanted to clarify some information in the datasheet. The datasheet specifies a "Power-down state supply current" of 1uA. I want to clarify, is this the total power…
Part Number: ADS7950 In the datasheet of the ADS79xx I noticed that the sampling instance is defined in Figure 1 and Figure 51 in two different ways.
Figure 1 shows that the sampling occurs at the falling edge of not(CS), whereas Figure 51 shows that the…
Part Number: ADS7950 Hi,
I want to know the way to read back the configuration settings from the ADS7950 to confirm that there is no change in settings during runtime. I could able to read only ADC data with channel information. Please help me on this…
Part Number: ADS7950 I am trying to do the above in the folowing way, only one ADC interrupt is working (the higher frequency)
the code I am using is as follows:
I DO NOT understand the conection between the timer and ADC that would make the ADC get triggered…
Part Number: ADS7950 we are planning to use an external 2.5V reference with 0.2% tolerance and will configure the device for 2Vref to sample 5V range input signals. however, i cannot find any details in the datasheet as to how accurate 2Vref is compared…
