Dear Angel, thanks a lot for your feedbacks on the schematic and the different mode in regard to the timings. I will now implement everything and get back to you once the system is in place if I have any issue. Please take care of your self and thanks a…
Part Number: ADS1220 Dear
I plan to use ADS1220 with single ended analog input in the range of 0- 3,2 Volts.
AVdd = 3,3 volts and DVdd = 3,3 volts.
Since Internal ref is limited to 2,048 Volts, Does the best solution is to connect external 3,3 volts Ref…
Hi Étienne,
This isn't specifically spelled out as computation time as several things are going on. In the section I referenced before (8.5.1.3) regarding DRDY it mentions where the pulse goes high for 2*tmod (note modulator periods and not tclk…
Part Number: ADS1220 Hello
I am configuring the ADC according to the following to read the input voltage provided at AIN0:
Config Reg 0: 0x81
Config Reg 1: 0x04
Config Reg 2: 0xD8
Config Reg 3: 0x00
I am using the ADC in unipolar mode: AVDD:5V; AVSS…
Part Number: ADS1220 Hi team,
In my customer application, the use the ads1220 with internal clock and the sps is been set as 1000 sps but for many ads1220 devices. Some will be 980 sps and the others may be 1020 sps , the clock pin connected to gnd by…
Part Number: ADS1220 Dear Expert
Due to the inconsistency between the configuration frequency and output data rate of the ADC chip ADS1220IPW in the pressure detection board, the board cannot be used normally. Exception description: The DR bit of software…
Hi Murdock,
I apologize for the delayed response.
Murdock Taylor said: Question 1 -- How long would it take for the analog settling at the ADC inputs and reference inputs -- typically? How long would it take for the invalid condition on IDAC compliance…
Part Number: ADS1220 Dears,
Customer Feedback that when they use ADS1220 ,end customer feedback below questions:
1. Now the ADS1220 is connected with a K-type thermocouple, and the temperature collected by the feedback from the end customer is very unstable…
Part Number: ADS1220 Hi,
I have customer who are having problems testing with the ADS1220.
The customer normally tests the ADS1220 current of about 10-12uA, but recently using the same test board to test another batch of chips found that the current reached…
Part Number: ADS1220 Hello : )
I was wondering if you can help me. I currently plan on having several SPI devices on the same bus - and some of these devices including the ADS1220 can have their supplies powered down. I'd like the devices on the bus that…
