Part Number: ADS1112 Hello
you specified Analog Inputs, A0, A1, Voltage to GND −0.3V to VDD + 0.3V. In my application the ADC inputs are connected to a 3V source by a 8k serial resistor. Could you said me wich is the IIn maximum current sinked on…
Part Number: ADS1112 Other Parts Discussed in Thread: ADS1120 Hi.
My customer using ADS1112 + LM285-2.5.
Schematic is attached.
1) When R36(1K) is not inserted, ADS1112's input port is damaged after few minutes. ADC2.5V is dropped about 1.2V.
2)…
Part Number: ADS1112 Hi Team,
My customer is running into an issue with the single conversion mode on the ADS1112 taking longer than 3x the sampling period:
Our firmware team is using the device in single-conversion mode, setting the ST/DRDY bit to 1…
Other Parts Discussed in Thread: ADS1112 , ADS1115 I've designed a project that uses the ADS1112 (using 3 channels in single ended mode).
Now there is the ADS1115 that can do the same and is a lot cheaper.
I know I'll have to change my layout and firmware…
Other Parts Discussed in Thread: ADS1112 Hi.
I have a question about ADS1112.
In below case,
Channel 1 : Differential AIN0, AIN1
Channel 2 : Differential AIN2, AIN3
Sometimes when I want to read ch1 data, ch2 data is read.
and
Sometimes when I want to…
Other Parts Discussed in Thread: ADS1112 Hi..
I am using ADS1112 in 16bit, 15sps, continous mode to find out the output code with respect to change in temperature. I am trying to find output code across Ain0 and Ain3 with Ain0 reading from a fixed voltage…

Other Parts Discussed in Thread: ADS1112 , ADS1115 Together with a DAC, I am using the ADS1112 in a fast closed measurement loop. I need to read from only 1 channel (Ain0) as fast as possible. What is the minimum delay I should set between I2C write to…
Other Parts Discussed in Thread: ADS1112 , ADS1115 Hi,
I have been going through the ADS1112 data sheet and have a question. If it is used in a single ended mode with AIN3 grounded, what is the maximum voltage on AIN0, AIN1 and AIN2 that can be correctly…
Other Parts Discussed in Thread: ADS1112 In my system,I want to measure 2 channels's voltage,I'm sure i have to send the right control command to ADS1112,I can correct read back the result of ads1112 and the contents of the control register ,bu…
