SGPLM386 - Audio Power Amplifier

General Description

The SGPLM386 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.

Key Features

  • Battery operation Minimum external parts Wide supply voltage range: 4V~12V Low quiescent current drain: 4mA Voltage gains: 20~200 Ground referenced input Self-centering output quiescent voltage Low distortion: 0.2% (AV=20, VS=6V, RL=8Ω, PO=125mW, f=1kHz).

Elektronische Bauelemente SGPLM386 Low Voltage Audio Power Amplifier RoHS Compliant Product A suffix of “-C” specifies halogen and lead-free DESCRIPTION The SGPLM386 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. 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 voltage supply, making the SGPLM386 ideal for battery operation.
