Product Summary

The LM394CH is a junction isolated ultra wellmatched monolithic NPN transistor pairs with an order of magnitude improvement in matching over conventional transistor pairs. The LM394CH was accomplished by advanced linear processing and a unique new device structure. Electrical characteristics of the LM394CH 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.

Parametrics

LM394CH absolute maximum ratings: (1)Collector Current: 20 mA; (2)Collector-Emitter Voltage: 35V; (3)Base-Emitter Current: ±10 mA; (4)Power Dissipation: 500 mW; (5)Junction Temperature：-25℃ to 85℃; (6)Storage Temperature Range: -65℃ to 150℃.

Features

LM394CH features: (1)Emitter-base voltage matched to 50 mV; (2)Offset voltage drift less than 0.1 mV/§C; (3)Current gain (hFE) matched to 2%; (4)Common-mode rejection ratio greater than 120 dB; (5)Parameters guaranteed over 1 mA to 1 mA collector current; (6)Extremely low noise; (7)Superior logging characteristics compared to conventional pairs; (8)Plug-in replacement for presently available devices.
