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.
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
Ωto 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.
8.2 Functional Block Diagram
8.3 Feature Description
There is an internal 1.35-KΩresistor 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.

9.2.1.1 Design Requirements
Table 1. Design Parameters
DESIGN PARAMETER EXAMPLE VALUE
Load Impedance 4 Ωto 32 Ω
Supply Voltage 5 V to 12 V
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-kΩresistor 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-kΩresistor). For 6 dB effective bass boost: R ~= 15 kΩ, the lowest value for good stable operation is R = 10
kΩif pin 8 is open. If pins 1 and 8 are bypassed then R as low as 2 kΩcan 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 kΩresistor. 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 kΩit 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 kΩresistor 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.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.

(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
