NTE1439 Overview
The NTE1439 is an integrated circuit in a 14 Lead DIP type package which logarithmically controls the throughput (gain) of an audio signal by the DC voltage or resistance value and has 2 circuits. Since voltage is internally stabilized, the stable operations are assured at the allowable supply voltage range (8V to 14.4V). The current source is provided with control circuit so that operation can be controlled by the...
