NTE15014
Integrated Circuit
Dual dbxII Noise Reduction System
Description:
The NTE15014 is an integrated circuit in a 22–Lead DIP type package designed for use in dbxII noise
reduction circuits for stereo applications. This device can be used for U.S. sound multiplex TV applications and low voltage operation (1.8V) allows the NTE15014 to be used in battery–operated Hi–Fi
equipment.
