Part Number: ADS1115 Hello,
Currently we are interfacing ADS1115 with ST32F446ZE micro-controller.
ADC Mode : Continuous conversion mode/Single ended input
configured alert pin as conversion ready signal. Controller will get external interrupt when conversion…
Part Number: ADS1115-Q1 Other Parts Discussed in Thread: ADS1115 Dear ADC team,
I have some questions about antialiasing filter when i read ADS1115-Q1 datasheet.
A typical application about ADS1115-Q1 is below. As we know, R5,R6,Cdiff Ccm1 and Ccm2 make…
Hi Aaron. Thanks for the very good advice. The problem was corrected by speeding up the data rate and removing the extra wait that was included when accessing ADS1115. As a result we are now running in single shot mode and 860sps.We are now watching it…
Part Number: ADS1115 Other Parts Discussed in Thread: ADS1256 Hi,
We are testing the ADS1115 with ESP32 for Pipe-to-Soil voltage in a cathodic protection monitoring system for buried pipeline. We could get a quite an accurate reading with direct connection…
Thanks for the reply!
Could you tell me one more thing? In the very first diagram I posted, the voltage across pins A0 and 1 is over 256mV each (although the voltage difference between the pins is about 25mV). Will this damage the ADS1115? As long as…
Part Number: ADS1115 Hello, when I use all channels I have to devide the max conversion /4, right? Eg.: 860SPS/4=215SPS per ch.
Do I get better resolution when I sample slower? If yes, is this documented?
Can I use continous mode when using all 4 channels…
Part Number: ADS1115 Hi,
I am using an ADC ADS1115 and I am using an high input impedance precision opamp as a voltage follower as opamp buffer before the ADC. The purpose of this setup is to measure feeble voltage of an electrochemical cell. Connecting…
Part Number: ADS1115 Hi everybody,
I have a question about voltage divider for ADS1115 single-ended sensor input. We have a sensor which gives output as 0.5vdc to 4.5vdc. We have MCU which is ESP32-wroom and and working 3.3VDC. I know from the datasheet…
