CM2038B
Description
: CM2038B 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 CM2038B 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.
