Part Number: ADS1220 Tool/software: Hi ,
I am try to make universal input device like ( 4-20 input ,Thermocouple K type ,J type ,RTD 2-wire , RTD 3-wire ,RTD-4 wire )
can any one suggest me circuit diagram for universal input .using ADS1220 or any other…
Hi Zabieru,
Have you tried measuring the voltage across the RTD and across the reference resistor with an oscilloscope? With the IDACs set at 250uA the voltage across the reference resistor should be around 1.2V and the voltage across the RTD should be…
Hi Sebastian,
Sebastian Sokolowski1 said: 1. "DRDY remains low but pulses high for a duration of 2 · t(MOD) prior to the next DRDY falling edge" What will happen when the pulse is observed during active SCLK? I know that with the first SCLK DRDY will go…
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…
Part Number: ADS1220 Other Parts Discussed in Thread: ISO6741 , Tool/software: Hello, i want to use ADS1220 with iso6741 and there is 4 pin for SPI isolation barrier. The question is do i need to use DRDY pin while using ADS1220 to read thermocouple?
Part Number: ADS1220 Other Parts Discussed in Thread: INA823 , REF2041 Section 8.5.2 of the data sheet describes the data output format as twos compliment but shows a +/-FS example that would be appropriate for a differential input setup where 0 is mid…
Part Number: ADS1220 Other Parts Discussed in Thread: ADS124S08 Hi Sir,
Our customer want to find a solution to replace AD4130-4. We suggest ADS1220 but our current spent higher than ADI device. Is there any suggestion to compete with AD4130-4? Thanks…
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…
