HT81697- Built in 30W boost mono

HT81697 is a built-in boost single channel Class D/AB audio power amplifier. When powered in series by two lithium batteries and boosted to 15.5V, THD+N=10%, it can continuously output 28W power (4 Ω load)。HT81697 has a built-in boost, which can provide a high voltage for the internal audio amplifier, thereby achieving higher power. Its boost value can be adjusted by external resistors HT81697 can be configured with boost current limiting values to prevent excessive current spikes。
