Other Parts Discussed in Thread: ADS1246 , REF5020 Hi
The ADS1246 requires an external voltage reference. Typical reference input current is specified as 30nA in the datasheet. The ADS1246 EVM document 'SBAU149B' shows a buffer between the VR and the ADC…
Hi Livio,
ADS1220 is an option as would be the ADS1146/47/47 or ADS1246/47/48. We have no insight to Digikey or Mouser Switzerland, so for part availability issues, you should revert back to the Customer Service Center. They should be able to help you…
Other Parts Discussed in Thread: ADS1248 , ADS1246 After I configure the ADC properly, I am able to get consistent readings.
If i want to change a configuration register, (say SYS0 for instance), I write the SDATAC and then a wait with DIN = '1'. I never…
Other Parts Discussed in Thread: ADS1246 , ADS1248 Question from customer:
Customer is wondering if the ADS1246 has some internal pull-up/down resistors on the digital inputs (especially on the START and RESET pins).
Regards,
Other Parts Discussed in Thread: ADS1246 , REF3020 , ADS1247 , REF5020 Hi everyone. I have some doubts about ADS1246 reference voltage. I have DVDD and AVDD connected to 3.3V. DGND and AVSS are connected to GND (0V). I have understood that Vref should be "(AVDD…
Other Parts Discussed in Thread: ADS1246 , MSP430F5438 Hi, I'm having problems reading the conversion result of my ADS1246. It's connected to a MSP430F5438.
Before commenting possible software problems, let's comment the hardware, because I'm not…
Other Parts Discussed in Thread: ADS1246
Greetings,
We are testing the ADS1246 (thanks for provide a sample :) ) in order to evaluate an imminent purchase for an european aerospace agency project.
I am capable of read any register and also to readout…
Other Parts Discussed in Thread: ADS1246 Hi!
I would like synchronize the convertions on two ADS1246. Apart from using the START input pin the datasheet states that there is the possibility of using the SYNC spi command for the same purpose. The spi communications…
Other Parts Discussed in Thread: ADS1246 Hi, there,
I wonder if you could help me on the following design choices:
1) have Vref close to the lower limit 0.5v (but above 0.5v) with PGA=2;
2) have Vref at about 2.4V (AVDD=5V, AVSS=0V) with PGA=16.
I see…
Other Parts Discussed in Thread: ADS1246 , ADS1259 I have an application that will need gain of 500-2000. Can I use LT1677 (ultra low noise) opamp to give it the additional gain? What care should I take for interfacing LT1677 to ADS1246? Do I need an anti…
