NATIONAL SEMICONDUCTOR -
Type: LM394H
Function: Junction isolated ultra well matched monolithic NPN transistor pair
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
Packaged in a round metal can, 6 pins Gold plated
TESTING:
To distinguish between the two devices, I have marked one underside with a - and the other a .
- LM394H
hFE (both transistors) 510 ~ 515
. LM394H
hFE (both transistors) 450 ~ 455
If the current gain is important to you, please select which LM394H you require (from the boxes on this page)
These devices are now stored embedded in ESD foam and within a sealed clear plastic packaging.
