The CST8002D is an audio power amplifier primarily designed for demanding applications in low-power portable systems. It is capable of delivering 3 watts of continuous average power to an 3Ω BTL load with less than 10%distortion (THD) from a 5VDC power supply. the CST8002D does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for audio systems and other low voltage applications where minimal power consumption is a primary requirement.
The CST8002D features a low-power consumption shutdown mode. the CST8002D contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions.
The CST8002D is unity-gain stable and can be configured by external gain-setting resistors.
The CST8002D can provide your USB subwoofer, radio, MP3 player, and loudspeaker perfect solution.
VDD=5V，RL=3Ω，Po=3W，THD+N≤10%
Wide operating voltage range: 1.5V~5.5V
Improved pop & click circuitry eliminates noise during turn-on and turn-off transitions
Available in space-saving packages: SOP-8
