Description
The C1316C is a dual audio power amplifier designed for portable audio sets.
A dual audio power amplifier is an electronic circuit or integrated circuit (IC) designed to amplify audio signals and drive two separate audio output channels, typically for stereo sound reproduction. It takes low-power audio signals as input and amplifies them to a level suitable for driving speakers or headphones. Dual audio power amplifiers are commonly used in a wide range of audio devices, including stereo amplifiers, home theater systems, car audio systems, and portable audio players.
These amplifiers can belong to different amplifier classes, such as Class A, Class AB, or Class D, each with its own advantages and trade-offs in terms of efficiency and linearity.
Features
1. Wide operation voltage range : Vcc = 3 to 16 V
2. High output power
3. High supply voltage rejection : SVR = 45 dB
4. Low quiescent current : Icc = 12mA
5. Low pop noise at power switch on and off.
