I am looking for accelerometer ultra low noise with low g.
I want to connect 4 sensors using I2C, so I need 2 pin SA0 and SA1.
Do you have such sensors

Hi, from my experience there isn't, if you want to connect multiple devices you need to use the SPI lines.
Otherwise, if you don't need to acquire signals simultaneously, you can use one of the accelerometers (for example the LIS2DW12) and read first from two of them, keeping the CS of the other two high and writing the I2C_DISABLE bit of the CTRL2 (21h) register to 1, in order to disable the I2C block. But I guess this is not the best solution ever.

Hi Janusz, for effective 14 or 16 bit resolution I believe you have to change package into the LIS2DW12, for example.
There was the LIS3DSH satisfying your requirements, but I believe it is nrnd now.
