SGSCLM386
Low Voltage Audio Power Amplifier
RoHS Compliant Product A suffix of “-C” specifies halogen and lead-free
DESCRIPTION
The SGSCLM386 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 SGSCLM386 ideal for battery operation.
FEATURES

Note:
1. All voltages are measured with respect to the ground pin, unless otherwise specified.
2. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which
the device is functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications
under particular test conditions which guarantee specific performance limits. This assumes that the device is within the Operating Ratings.
Specifications are not guaranteed for parameters .
