CJMCU9812 MAX9812L Microphone Amplifier Sensor Module
MAX9812 is a single / double input£¬ 20dB fixed gain microphone amplifier. They have small package size£¬ built-in low noise Microphone Bias£¬ suitable for portable audio devices such as notebook computers£¬ mobile phones£¬ handheld computers and so on. The amplifier gain bandwidth product is 500kHz£¬ the output can be up to a full swing£¬ with the industry's top level of 100dB power supply rejection ratio£¬ very low THD+N (0.015%). Also has a series of power saving characteristics: only 230 A supply current£¬ the overall shutdown mode can be the power supply current and bias current sum to 100nA.When the ratio of 100dB to suppress the power 217HzAs low as 0.015% THD+NMAX9812L/MAX9813L:2.7V to 3.6VMAX9812H/MAX9813H:4.5V to 5.5VBuilt in low noise microphone bias sourceMAX9812L/MAX9813L:2.3VMAX9812H/MAX9813H:4.0V100nA low power shutdown modeFull swing output20dB fixed gain
