SGM4863 datasheet

Description

SGM4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W into a 4Ω load or 2.5W into a 3Ω load with typically 1% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.

To simplify audio system design, the SGM4863 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.

 

Features

1. 2.5W into 3Ω Load from 5V Power Supply at THD+N = 1% (Typical, per Channel)

2. 2.1W into 4Ω Load from 5V Power Supply at THD+N = 1% (Typical, per Channel)

3. 1.3W into 8Ω Load from 5V Power Supply at THD+N = 1% (Typical, per Channel)

4. Low Shutdown Current: 0.03μA

5. Operation Supply Voltage: 2.8V to 5.5V

6. Stereo Headphone Amplifier Mode

2SC3320 transistor datasheet

Description

2SC3320 Transistor is a semiconductor device used to amplify or convert electronic signals and power. It usually consists of a semiconductor material with three or more terminals for connection to external circuitry. A voltage or current applied to one pair of transistor terminals controls the current flowing through the other pair of terminals.
