LM394 Product details

Description

The LM194 and LM394 are junction isolated ultra wellmatched monolithic NPN transistor pairs with an order of magnitude improvement in matching over conventional transistor pairs This was accomplished by advanced linear processing and a unique new device structure Electrical characteristics of these devices such as drift versus initial offset voltage noise and the exponential relationship of base-emitter voltage to collector current closely approach those of a theoretical transistor Extrinsic emi

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 conventional pairs Plug-in replacement for presently available devices Typical.
