LM194 LM394 Supermatch Pair December 1994 LM194 LM394 Supermatch Pair General 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 emitter and base resistances are much lower than presently available pairs either monolithic or discrete giving extremely low noise and theoretical operation over a wide current range Most parameters are guarant
