The NTE1391 from NTE Electronics is an integrated circuit designed as a 12W audio power amplifier, suitable for car radio and car stereo applications. It boasts high gain, typically 51dB, and a high power output of 12W. The design requires a low number of external components and features soft tonal quality even at saturated power output.
Key features include low distortion across the audio frequency range and low residual noise. The NTE1391 incorporates built-in audio muting circuits (AC Mute & DC Mute) and comprehensive protection circuits, including thermal protection, overvoltage and surge voltage protection, load short-circuit current limiting, and output pin DC short-circuit protection. The NTE1391 is a mirror image pinout of the NTE1390.
Recommended operating conditions include a supply voltage of 13.2V and a load resistance between 4Ω and 8Ω. The absolute maximum supply voltage is 25V quiescent and 18V with signal. Allowable power dissipation is 25W at 75°C case temperature, with a junction-to-case thermal resistance of 3°C/W. The operating temperature range is -20°C to +75°C.
