Part Number: ADS1112 Hi all I am using ADS1112 in 16bit, 15sps, single mode. I am trying to find output code across Ain0 and Ain3 with Ain0 reading from a constant voltage source (in my case grounded in order to test the chip) and Ain3 witch is grounded…
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 the…
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.…
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…
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…
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…
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…
Hi Vijeth,
Let's start with your last question first and work backwards. Can you ever get zero result with the input at zero? There is the condition of noise and how it affects the result. Noise in the supply, noise in the ground, and noise of the reference…
Sarfraz,
Welcome to the forum! The largest voltage that you can measure is 2.048V. The absolute input voltage that can be applied is VDD+0.2V. For example if VDD is 5V you can place more than 2.048V on the input, but and value returned will be a full…
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…
