1. The gain is internally 6 dB higher than what measured at the test output. This is due to the differential to single-ended

conversion used for the test output.

2. The current is generated by a PTAT (proportional to absolute temperature) source, and has therefore a temperature

dependency described by: ∆I/Io = ∆T/To, with Io being the current at ambient temperature (25 °C) and To the ambient

temperature (25 °C) expressed in Kelvin, that is 298K.
