HT8698 Description

Short technical summary and product information.

The HEROIC HT8698 is a versatile stereo audio amplifier IC featuring a Class D design with an integrated boost converter. It delivers up to 2x4.75W of continuous power into a 4-ohm speaker when operating from a Li-battery voltage boosted to 6V. The boost output voltage is adjustable, offering design flexibility.

Key features include an Anti-Clipping Function (ACF) that automatically detects and suppresses output signal clipping, improving sound quality and protecting speakers. The HT8698 also supports a Class AB amplifier mode, which can be switched to mitigate EMI interference from the Class D operation and boost converter. Its filter-less modulation circuit allows for direct speaker driving with low distortion and noise, enabling simpler circuit designs with fewer external components, ideal for portable applications.

Protection features include thermal protection, over-current protection, and low voltage malfunction prevention. The device is available in a Pb-Free TSSOP20L-PP package and supports independent shutdown and mute functions to minimize power consumption.

Applications for the HT8698 include Bluetooth speakers, portable speakers, 2.1 channel systems, megaphones, MP4 players, GPS devices, tablet PCs, notebooks, smartphones, and LCD TVs/monitors.
