LM386 Low Voltage Audio Power Amplifier
1 Features
3 Description
•
•
•
The LM386M-1 and LM386MX-1 are power amplifiers
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.

Battery Operation
Minimum External Parts
Wide Supply Voltage Range: 4 V–12 V or
5 V–18 V
Low Quiescent Current Drain: 4 mA
Voltage Gains from 20 to 200
Ground-Referenced Input
Self-Centering Output Quiescent Voltage
Low Distortion: 0.2% (AV = 20, VS = 6 V, RL = 8 Ω,
PO = 125 mW, f = 1 kHz)
Available in 8-Pin MSOP Package
The inputs are ground referenced while the output
automatically biases to one-half the supply voltage.
The quiescent power drain is only 24 mW when
operating from a 6-V supply, making the LM386M-1
and LM386MX-1 ideal for battery operation.

8 Detailed Description
8.1 Overview
The LM386 is a mono low voltage amplifier that can be used in a variety of applications. It can drive loads from 4
Ω to 32 Ω. The gain is internally set to 20 but it can be modified from 20 to 200 by placing a resistor and
capacitor between pins 1 and 8. This device comes in three different 8-pin packages as PDIP, SOIC and VSSOP
to fit in different applications.

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 Detailed Design Procedure section.
8.4 Device Functional Modes
As this is an Op Amp it can be used in different configurations to fit in several applications. The internal gain
setting resistor allows the LM386 to be used in a very low part count system. In addition a series resistor can be
placed between pins 1 and 5 to modify the gain and frequency response for specific applications.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
Below are shown different setups that show how the LM386 can be implemented in a variety of applications.
9.2 Typical Application
9.2.1 LM386 with Gain = 20
Figure 10 shows the minimum part count application that can be implemented using LM386. Its gain is internally
set to 20.

9.2.1.2 Detailed Design Procedure
9.2.1.2.1 Gain Control
To make the LM386 a more versatile amplifier, two pins (1 and 8) are provided for gain control. With pins 1 and 8
open the 1.35-kΩ resistor sets the gain at 20 (26 dB). If a capacitor is put from pin 1 to 8, bypassing the 1.35-kΩ
resistor, the gain will go up to 200 (46 dB). If a resistor is placed in series with the capacitor, the gain can be set
to any value from 20 to 200. Gain control can also be done by capacitively coupling a resistor (or FET) from pin 1
to ground.
Additional external components can be placed in parallel with the internal feedback resistors to tailor the gain and
frequency response for individual applications. For example, we can compensate poor speaker bass response by
frequency shaping the feedback path. 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 used. This restriction is because
the amplifier is only compensated for closed-loop gains greater than 9.

9.2.1.2.2 Input Biasing
The schematic shows that both inputs are biased to ground with a 50 kΩ resistor. The base current of the input
transistors is about 250 nA, so the inputs are at about 12.5 mV when left open. If the dc source resistance driving
the LM386 is higher than 250 kΩ it will contribute very little additional offset (about 2.5 mV at the input, 50 mV at
the output). If the dc source resistance is less than 10 kΩ, then shorting the unused input to ground will keep the
offset low (about 2.5 mV at the input, 50 mV at the output). For dc source resistances between these values we
can eliminate excess offset by putting a resistor from the unused input to ground, equal in value to the dc source
resistance. Of course all offset problems are eliminated if the input is capacitively coupled.
When using the LM386 with higher gains (bypassing the 1.35 kΩ resistor between pins 1 and 8) it is necessary
to bypass the unused input, preventing degradation of gain and possible instabilities. This is done with a 0.1 μF
capacitor or a short to ground depending on the dc source resistance on the driven input.

10 Power Supply Recommendations
The LM386 is specified for operation up to 12 V or 18 V. The power supply should be well regulated and the
voltage must be within the specified values. It is recommended to place a capacitor to GND close to the LM386
power supply pin.
