NTE826
Integrated Circuit
TV Sound System, 2W
Description:
The NTE826 2W sound IF circuit is designed for television and related applications. The circuit is
comprised of 2 independent functions: a sound IF and an audio power amplifier. The sound IF portion
of the circuit utilizes circuitry similar to the NTE712. An improved volume control circuit is included,
however, so that recovered audio is a linear function of the resistance of the control potentiometer.
Audio power amplification is accomplished with circuitry similar to the popular NTE740A audio power
amplifier, featuring both short circuit and thermal protection.
Features:
D Minimum Undistorted Output: 2W
D Linear Volume Control: 75dB range
D Fixed Voltage Gain in Audio Amplifier
D Short Circuit and Thermal Protection
