Part Number: ADS1115 Tool/software: Hello,
I am using an ESP32 along with 4 ADS1115 modules. I have successfully obtained the I2C addresses 0x48, 0x49, and 0x4A, and I can correctly read the analog channels from each of them. However, I am unable to…
Part Number: ADS1115 Having some problem with few ADS1115 on my PCB. All of them is behaving the same, so I suspect there is a communication error somewhere.
As you see, I get a value around 1.2v (1.20003662221137) which is very exact every time. Also…
Hi Jiang,
I took a look at the new schematic.
The FSR of ±0.512V should be okay for the range you want to measure (20-100mV). FSR = ±0.256 V would work as well.
I see potential problems with having the resistor divider network at the inputs…
Part Number: ADS1115-Q1 Other Parts Discussed in Thread: ADS1015 Hi teams:
I'm using MSP430 with ADS1015 for data acquisition, with I2C communication interface. I need to collect data from three channels in total. I found an issue that MSP430 sequentially…
Part Number: ADS1115
I'm working on a new design where we have an ADS1115 connected via I2C to a SoC through a level translator (1.8V at the SoC, 3.3V at the ADS1115). When attempting to read from the device, either the config or conversion register…
Part Number: ADS1115 Other Parts Discussed in Thread: ADS1119 Tool/software:
Hi everyone.
I'm looking for a simple to use chip that allows me to read only the precise voltages of 4 lithium batteries in series with each other (in 4S configuration as…
Part Number: ADS1115 Tool/software: Hi everyone. I find myself facing a voltage measurement circuit of 4 lithium batteries in series (16.80V total).
Initially I opted for a Single Mode measurement, therefore measuring each battery from the positive to…
Part Number: ADS1115L Other Parts Discussed in Thread: ADS1115 Tool/software: Hello E2E Experts,
Good day.
I am using ADS1115 for measuring the negative voltage and positive voltage in differential mode and also in single channel mode. The configuration…
