NTE1802
Integrated Circuit
Power Amplifier for Car Stereo Radio,
12W/Ch or 24W BTL
Description:
The NTE1802 is an integrated class–B output amplifier in a 13–Lead SIP type package. This device
contains two identical amplifiers with different input stages which can be used for stereo or bridge ap-
plications. The gain of each amplifier is fixed at 20dB. A special feature of the NTE1802 is the mute/
stand–by switch.
