HT8313
FEATURE
- HT8313 GENERAL DESCRIPTION
- Anti-Clipping Function (ACF)
- Adaptive Charge Pump Regulator
HT8313 is a Class D audio amplifier which can deliver continuous 5.5W output power into a 4Ω speaker with 5V power supply when THD+N = 10%.
- Maximum Voltage Gain: 28d B
The class D audio amplifier’s power supply is
- Output Power (Class D) adaptively boosted by the integrated charge pump regulator which only works while the output power
5.5W (VBAT=5V, RL=4Ω, THD+N=10%) is big enough. This will significantly extend the
4.5W (VBAT=5V, RL=4Ω, THD+N=1%)
- Output Power (Class AB)
2.8W (VBAT=5V, RL=4Ω, THD+N=10%) 2.3W (VBAT=5V, RL=4Ω, THD+N=1%)
