NTE1687
Linear Integrated Circuit
Dual, 2.5W (7.8W BTL) Audio Amp
Description:
The NTE1687 is a high performance stereo power amplifier in an 11鈥揕ead SIP type package de-
signed to deliver 1W/Ch into 4鈩?or 2W bridged monaural into 8鈩? It is ideal for sensitive AM radio
applications, exhibiting lower wideband noise, lower distortion, and less AM radiation than conven-
tional designs.
