The next circuit shows a similar design as above, except that its pins 1 and 8 have been connected to a capacitor of 10uF, which as explained above helps to pull the gain of the amplifier to 200 Detailed LM386 Circuit Diagram with Instructions Application Circuits From the above discussion w...
UNISONIC TECHNOLOGIES CO., LM386 LINEAR INTEGRATED CIRCUIT LOW VOLTAGE AUDIO POWER AMPLIFIER DESCRIPTION The UTC LM386 is a power amplifier, 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 ...
This is done with a series RC from pin 1 to 5 (paralleling the internal 15 kΩ resistor). For 6 dB effective bass boost: R=15 kΩ, the lowest value for good stable operation is R=10 kΩ, if pin 8 is open, If pins 1 and 8 are bypassed then R as low as 2 kΩ can be ...
8.2 Functional Block Diagram Gain Circuitry - + Bias Circuitry Bypass 8.3 Feature Description There is an internal 1.35-KΩ resistor that sets the gain of this device to 20. The gain can be modified from 20 to 200. Detailed information about gain setting can be found in the Section 9.2....
