NTE NTE807

NTE807
Integrated Circuit
TV Sound Channel, 1W
Description:
The NTE807 is a complete 1Watt sound channel in a 16–Lead DIP type package and is ideally suited
for use in small screen TV or mobile FM radios. This device operates from a single 14V supply and
provides VCC/2 output tracking as well as greater than 20dB of ripple rejection. The NTE807 will directly drive an 8Ω or 18Ω speaker and has a true 1W output into the 8Ω load.
Features:
D Low Limiting Threshold
D Low External Parts Count
D High AM Rejection
D Single Adjustment Tuning
D 70dB Limiter Gain
D 70dB DC Voltage Control Range
D Automatic Thermal Shutdown
D Output Current Limiting
D 10V to 18V Operating Range
D > 20dB Ripple Rejection
