NTE15014
Integrated Circuit
Dual dbxII Noise Reduction System
Description:
The NTE15014 is an integrated circuit in a 22鈥揕ead 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 ap-
plications and low voltage operation (1.8V) allows the NTE15014 to be used in battery鈥搊perated Hi鈥揊i
equipment.
