Description: The NTE823 is an audio power amplifier in an 8–Lead DIP type package designed for use in low volt age consumer applications.
Implement this LM386N-3/NOPB class D amplifier from Texas Instruments for a stronger and more powerful output sound. Its maximum power dissipation is 1250 mW. It has a differential input signal and a single output signal. It has a maximum load resistance of 32 Ohm. It has a 1-channel mono output. This audio amplifier has a minimum operating temperature of 0 °C and a maximum of 70 °C. Its typical PSRR is 50 dB. This device uses a single power supply.
The LM386N-1/NOPB is a Wide Vin Class-D low Power Audio Amplifier with internal gain designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200. The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24mW when operating from a 6V supply, making the LM386 ideal for battery operation.
