CM4890/LM4890 0.
8W Mono Class AB Audio Amplifier General Description: CM4890 is an audio amplifier of class AB，when connected to a 4.
5V ，THD+N less than 10%，will deliver0.
8W to 4Ω load or 0.
5W to a 8Ω load .
The CM4890 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.
