Integrated Circuit  
Dual 12W/Channel Audio Power Amplifier  
Description:  
The NTE1850 is a dual Hi–Fi audio power amplifier in a 9–Lead SIP type package designed for  
mains–fed applications such as stereo TV sound and stereo radio. The circuit is optimal for symmetri-  
cal power supplies but is also well suited to asymmetrical power supply systems. An output power  
of 2 x 12W (THD = 0.5%) can be delivered into an 8load with a symmetrical power supply of ±16V.  
The gain is fixed internally at 30dB, but can be changed externally if required. Internal gain fixing gives  
low gain spread and very good balance between the amplifiers (0.2dB).  
A special feature is an input mute circuit which provides suppression of unwanted signals at the inputs  
during switching on and off. This circuit disconnects the non–inverting inputs when the supply voltage  
is below ±6V, while allowing the amplifiers to remain in their DC operating condition.  
Two thermal protection circuits are provided, one monitors the average junction temperature and the other  
the instantaneous temperature of the power transistors. Both protection circuits activate at +150°C, allow-  
ing safe operation to a maximum junction temperature of +150°C without added distortion.
