Hi, bob I want to close this thread with a thank you note. ADS1120S is working fine as of now. thanks for your overall support and quick replies. Your quality of support is indeed top-notch!
Part Number: ADS1120-Q1 Other Parts Discussed in Thread: ADS1120 Hi Experts,
I use ADS1120-Q1 with an ARM-M0 MCU's SPI. It's the only device on the SPI bus with din dout sclk and cs. /DRDY is connected but not used. ADC's clk pin is tight to GND. ADC…
Part Number: ADS1120 Hi, team,
My customer is using ADS1120 for K-type thermocouple measurement. And they adopt below circuit from datasheet, using internal reference. RB1 and RB2 is 1Mohm.
They found the measured temperature is always 0.9degC higher…
Part Number: Team,
I am still confused about the application of ADS1120， so I would like to list more questions:
1. What is the function AVDD and AVSS? Where do they connect to?
2. What is the function of VREF if choose internal VREF?
3. If AVDD is tied…
Part Number: ADS1120 Team,
Customer is using ADS1120 in the battery pack, and they need to use ADS1120 to measure bi-directional current. Now they are wondering whether ADS1120 could measure negative differential input signal? Customer have found that…
Part Number: ADS1120 Hello,
I would like you to confirm whether you have following data or not.
* Over 200Hz filter characteristic of figure 52 (Filter Response (DR = 20SPS))
We would like to know filter characteristic up to 256kHz (fmod of normal mode…
Part Number: ADS1120-Q1 Other Parts Discussed in Thread: ADS1120 Hi,
I used the ADS1120 to measure thermistor (from 100ohm to 300kohm).
I used a ratiometric schematic, the voltage reference is AVDD = 5V. Component is configured to used the AVDD voltage as…
Part Number: ADS1120-Q1 Hi,
We measure with reference to AINn. I will therefore assume that we do an offset calibration with reference to AINn. Do we still need to do an offset calibration with reference to (AVDD + AVSS)/2? I do not really see the need…
Part Number: ADS1120 Hi experts:
My customer is designing with ADS1120. To filter out the noise they use a serial 220ohm resistor between 3.3V supply and DVDD pin. The DVDD voltage is initially 3.3V after power up and before configuration the device,…
Part Number: ADS1120 Other Parts Discussed in Thread: ADS1119 , ADS112C04 , ADS122U04 , ADS114S06B Hi all
My customer is looking for a cost-effective 4-channel ADC, 16-Bit, 1ksps sufficient.
The ADS1120 seems to fit. Are there other options you can suggest…
