Description

The AW88461CSR is an I2S/TDM input, high efficiency digital Smart K audio amplifier with an integrated 12V smart boost converter. Due to its 8uV noise floor and ultra-low distortion, clean listening is guaranteed. It can deliver 6.5W output power into an 8Ω speaker at 1% THD+N. The AW88461CSR integrates a high-efficiency smart boost converter as the Class-D amplifier supply rail. The output voltage of boost converter can be adjusted smartly according to the input amplitude, which extremely improves the efficiency without clipping distortion. The AW88461CSR features high RF suppression and eliminates TDD noise completely benefited from the digital audio input interface. General settings are communicated via an I2C-bus interface, and the device address is configurable. The AW88461CSR offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection and Over-Voltage Protection to protect the device. AW88461CSR is available in a WLCSP 2.2mmX2.2mm-36B Package.
