NTE NTE1606 Datasheet
NTE1606
Integrated Circuit
Dual Audio Power Amplifier, 4W to 7W
Description:
The NTE1606 is an audio power amplifier integrated circuit in a 12–Lead SIP type package specifically designed for cassette radio applications. This device delivers 4.3W per channel under a 12V power
supply and 6.8W under a 15V power supply to a 4Ω load.
Features:
D Low Quiescent Current for Efficient Battery Operation
D Audio Muting Circuit Included
D Designed for Low Crossover Distortion Under a Low Idling Current
D No Electrical Isolation Needed for Simple Chassis Mounting
D Internal Thermal Protection
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
