Click here to ask an associate for production status of specific part numbers. Microphone Amplifier with AGC and MAX9814. Low-Noise Microphone Bias General Description Features The MAX9814 is a low-cost, high-quality Microphone Automatic Gain Control (AGC). Amplifier with automatic gain control (AGC) and Three Gain Settings (40dB, 50dB, 60dB). low-noise Microphone bias. The device features a low-noise preamplifier, variable gain Amplifier (VGA), output Programmable Attack Time Amplifier , Microphone -bias-voltage generator, and AGC Programmable Attack and Release Ratio control circuitry. to Supply Voltage Range The low-noise preamplifier has a fixed 12dB gain, while Low Input-Referred Noise Density of 30nV/ Hz the VGA gain automatically adjusts from 20dB to 0dB, Low THD: (typ). depending on the output voltage and the AGC threshold. The output Amplifier offers selectable gains of 8dB, 18dB, Low-Power Shutdown Mode and 28dB. With no compression, the cascade of the Internal Low-Noise Microphone Bias, 2V.
General Description The MAX9814 is a low-cost, high-quality microphone amplifier with automatic gain control (AGC) and low-noise microphone bias.
