CM8602B 2.4W Audio Amplifier Stereo General Description: CM8602B is an audio amplifier of class AB，when connected to a 5V supply，THD+N less than 10%，will deliver 2.4W to a 4Ω load or 1.5W to a 8Ω load . The CM8602B is unity-gain stable and can be configured by external gain-setting resistors, It features a low-power consumption shutdown mode with very low shutdown current, and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and pops” during device turn-on and turn-off. It can also be applied in headphone function mode. Features: 1. 2. 3. 4. 5. 6. Power output at 5V supply, 4Ω load, THD+N<10%，is 2.4W. Power output at 5V supply, 8Ω load, THD+N<10%，is 1.5W. Operating supply voltage: VDD =2.2V~5.5V。 Typical shutdown current: 0.2uA。 Improved pop & click circuitry eliminates noise during turn-on and turn-off transitions SOP-16 packages.

If connecting headphones to the headphone jack, the voltage applied to HP-IN pin is pulled up to VDD by resistor R11, this enables the headphone function, and mutes the bridged speakers. 音频功放专业供应商,欢迎洽谈. 0755-83978192 http://xinruihk.ic37.com CM8602B Package Information SOP-16 7¢X (4X) e D y E NOTE 1.
