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 resistor and
capacitor between pin 1 and pin 8 will increase the gain to any value
up from 20 to 200 dB.
The inputs are ground referenced while the output automatically
biases to one-half the supply voltage. The quiescent power drain is
only 24 milliwatts when operating from a 6 volt supply, making the
LM386 ideal for battery operation.
FEATURES

Notes: 1: Twist Supply lead and supply ground very tightly.
2: Twist speaker lead and ground very tightly.
3: Ferrite bead in Ferroxcube K5-001-001/3B with 3 turns of wire.
4: R1C1 band limits input signals.
5: All components must be spaced very closely to IC.
