HT862
FEATURES
- Automatic Gain Control (AGC) with Battery Tracking and Limiter function
- Battery Tracking: automatically reduce system gain to extend battery life when the battery voltage is low
- Limiter: adjusts the amplifier gain to prevent heavy clipping
- Integrated Adaptive Boost Converter
- Increases efficiency at low output power
- Integrated Thermal Foldback (TFB) function
- Particularly apply to applications of 7.85V+Class D, Boost + Class AB or one with a weak thermal system, significantly increase the peak audio power
- Low quiescent current of 4.0m A (VBAT = 3.6V)
- Efficiency: 88% (VBAT = 4.2V, RL = 4Ω+22u H, Po = 0.6W)
- THD+N: 0.02% (VBAT = 3.6V, RL = 4Ω+22u H, Po = 0.5W, Class D)
- Control Mode :Hardware or I2C
- Power Supply/Output
- VBAT from 2.8V to 5.0V
- Multiple Boost Output VPOUT Settings: 5.45V, 6.45V, 7.45V, 7.85V
- Output Power 3.4 W (VBAT=4.2V, VPOUT = 5.45V, RL=4Ω,
THD+N=1%) 4.7 W (VBAT=4.2V, VPOUT = 6.45V, RL=4Ω,
THD+N=1%) 6.2 W (VBAT=4.2V, VPOUT = 7.45V, RL=4Ω,
THD+N=1%)...
