Features

* Y Y Y Y Y Y Y Y Emitter-base voltage matched to 50 mV Offset voltage drift less than 0 1 mV C Current gain (hFE) matched to 2% Common-mode rejection ratio greater than 120 dB Parameters guaranteed over 1 mA to 1 mA collector current Extremely low noise Superior logging characteristics compared to

Applications

* To guarantee long term stability of matching parameters internal clamp diodes have been added across the emitterbase junction of each transistor These prevent degradation due to reverse biased emitter current the most common cause of field failures in matched devices The parasitic isolation junction
