Audio Amplifiers CS4412A

The CS4412A integrates on-chip over-current, undervoltage, over-temperature protection and error reporting as well as a thermal warning indicator. The low R_DS(ON) outputs can source up to 2.5 A peak current, delivering high efficiency which allows the use of small device package and lower power supplies. The CS4412A is available in a 48-pin thermally enhanced QFN package and the CRD4412A customer reference design is also available

The CS4412A is a high-efficiency power stage for digital Class-D amplifiers designed to input PWM signals from a modulator such as the CS4525. The power stage outputs can be configured as four half-bridge channels, two half-bridge channels and one full-bridge channel for 2.1 stereo, two full-bridge channels for 2.0 stereo, or one parallel full-bridge channel for mono configuration.
