Other Parts Discussed in Thread: ADS1246 Hi,
There are some issues regarding the SPI data comunication on ADS1246/7/8. Datasheet is not clear about the number of CLKs needed with some commands:
SYNC - 16 CLKs with CS low or 2 x 8 CLKs with CS low on each…
Other Parts Discussed in Thread: ADS1246 I am workign with ADS1246 data converter. Powering up the chip and using SPI bus I am able to read A2D data. I assume the defult register values allow the converstion take place and I do get reasonable conversition…
Other Parts Discussed in Thread: ADS1246 , ADS1118 , ADS1247 , ADS1248 Hi
We are using the ADS1246 as a high precision A/D converter for a battery system.
Can you clarify under which conditions it is required that the inputvoltage is above AVSS+0,1V. Right…
Other Parts Discussed in Thread: ADS1246 , CONTROLSUITE Hi,
I must apologize as I have very little experiance with the SPI protocol. I am also aware that I can use the McBSP for SPI/DMA purposes.
I am using a ADS1246 ADC as I do not have enough resolution…
Other Parts Discussed in Thread: ADS1246 , INA826 , ADS1255 , LM317 I want ADS1246 to measure a voltage start from 0, for example, VINN=0, VINP from 0 to 2V. Datasheet gives the balanced bipolar supplies as VDD=2.5V and VSS=-2.5V, it is good. But because…
Other Parts Discussed in Thread: ADS1246 , ADS1118 , ADS1247 , TMP102 , TMP112 , INA333 Can the ADS1246 be used for accurate, high resolution thermocouple measurements? The data sheet mentions that the PGA can be set to 128:1 and that it has an on-board temperature…
Other Parts Discussed in Thread: ADS1246 , MSP430F2274 Support,
I am working with the ADS1246 and I am experiencing some difficulties with the chip. I have a strain gage connected to the ADS, and the ADS connected digitally to a MSP430F2274. In order to…
Other Parts Discussed in Thread: ADS1246 , MSP430F2274 I am experiencing a strange problem. I am using the ADS1246, I have the unit on a custom PCB and the unit is mostly fully functional except for the issue that I am now having.
The problem is very strange…
Other Parts Discussed in Thread: ADS1246 I am using an ads1246 for my application to read voltage. It seems everything runing ok, I can set the registers and read them back with the correct values. The problem is the reading is not right. Here is some of…
Ben,
This is normal behaviour. The START pin powers up the device and starts conversions. Even if you use SDATAC, the DRDY signal will always be active, and the data will be valid. What I do in this case is to deactivate the interrupt when I do register…
