I'm looking to understand how to read the noise spec of the INA103 (and others). It's expressed as e.g. 1 nV/√Hz. Does this signify that at 1MHz, I would expect as much as 1uV (1nV * √1000000) of noise? If so, I'd appreciate recommendations of alternative differential amplifiers I could use with lower noise in the band 0.2-5MHz?
