Description

The AW88699QNR is an I2S/TDM input, high efficiency digital Smart K audio amplifier with an integrated 15V smart boost converter. Due to its 7μV noise floor and ultra-low distortion, clean listening is guaranteed. It supports 2S battery connection and can deliver 14W output power into a 4Ω speaker at a battery voltage of 8.4V. The AW88699QNR 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 AW88699QNR 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 AW88699QNR offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection and Over-Voltage Protection to protect the device. The AW88699QNR features Power Saving Mode (PSM), a feature developed specifically for batteries life extension, which helps reduce power consumption and noise during small output. By switching output power rail according to different input amplitude, system can achieve a better performance of efficiency and noise. AW88699QNR features Power Off Sound(POS) and Low Power Mode(LPM), a feature developed for self-tone generation and power save.
