Bit-volt conversion factor

[SHIVANI]

I am currently working on the data conversion between bit values and microvolts. Could someone please verify the bit_volt conversion factor? My understanding is that it should be 0.195.

Thank you for your time and expertise.

The conversion factor depends on the type of data being recorded, and is saved in the .oebin file for each channel. But if you are analyzing electrophysiological signals recorded using the Open Ephys Acquisition Board or Neuropixels probes, then indeed multiplying the original 16-bit integers in the .dat file by 0.195 will convert the values to microvolts.
