Function to_nanovolts 

pub fn to_nanovolts(pga: Pga, raw: i16) -> i64

Converts a raw conversion result to nanovolts at the selected full-scale range.

The result is a 16-bit two’s-complement code spanning plus or minus the full scale, so the voltage is code * full_scale / 32768. Working in nanovolts keeps the conversion exact in integer arithmetic across every gain setting.

Arguments

• pga - the gain the conversion was taken at.
• raw - the signed conversion register value.

Returns

The measured voltage in nanovolts.
