HT8787B- Built in Booster 2 × 9.0W stereo

HT8787B is a stereo D-class audio power amplifier with built-in adaptive boost. It is powered by a lithium battery and can continuously output 2 under 1kHz signal conditions, with THD+N=1% and VPOUT=8.4V boost × 7W power (4 Ω load) The HT8787B has a built-in G-class boost, which can be set to the maximum boost value to meet different output power requirements. This boost does not boost during small music signals, but only works when the power is high. It can greatly improve system efficiency and extend battery life
    1. Adjustable amplitude limiting function
    -Free configuration of audio limitation amplitude to limit the output audio signal to a fixed distortion level
    2. Built in automatic temperature limiting control function
    -Adapt to different heat dissipation conditions and avoid overheating shutdown phenomenon
    3. Efficient adaptive G-class boost function, effectively extending playback time
    4. Adjustable maximum current limit value, effectively preventing battery from stalling
    5. Adjustable boost value
    6. THD+N: 0.05% (RL=4 Ω, fIN=1kHz, Po=2) × 1.0W)
    7. Low static current: 7mA, 3.7V ・ Output power (VBAT=3.7V, fIN=1kHz, RL=4 Ω)
    two × 7W (VPOUT=8.4V, THD+N=1%) 2 × 9W (VPOUT=8.4V, THD+N=10%)
    8. VBAT power supply range: 2.9V to 8.5V
    9. Three gain options: 21dB, 25.5dB, 30dB
    10. Filter free digital modulation, directly driving the speaker
    11. Protection function: overcurrent/overheating/undervoltage abnormal protection function
    12. Lead free and halogen-free packaging, TSSOP20L-PP
