MAX9814 Microphone AGC Amplifier Module
Product Code: SNM094Category: Sensor Modules
MAX9814 Microphone AGC Amplifier Module is a high-performance automatic gain control(AGC)designed for audio applications requiring low noise,low distortion,and high gain stability.
MAX9814 Microphone AGC
Amplifier Module
Description:
The MAX9814 Microphone AGC Amplifier Module is
a high-performance automatic gain
control (AGC) amplifier designed for audio applications requiring low noise, low distortion, and high gain stability.
With a selectable gain of 40dB, 50dB, or 60dB,
it automatically adjusts the microphone signal for optimal clarity while
minimizing distortion. Its low-noise
built-in microphone bias (2V) and programmable attack/release ratios make
it an excellent choice for voice
recording, audio surveillance, and noise-sensitive applications.
Operating on a 2.7V - 5.5V supply voltage, it offers
a wide frequency response (20Hz -
20kHz), ensuring high-fidelity audio capture. The low-power shutdown mode makes it
suitable for battery-powered projects.
Specifications:
· Power Supply Voltage: 2.7V - 5.5V
· Current Consumption: 3mA
· Output Voltage: 2Vpp on 1.25V bias
· Frequency Response: 20Hz - 20kHz
· Attack & Release Ratio: Programmable
· Gain Control: 40dB / 50dB / 60dB (Selectable)
· Input Noise Density: 30nV/√Hz
· Total Harmonic Distortion (THD): 0.04% (typical)
· Shutdown Mode: Low-power mode available
· Microphone Bias: 2V low-noise built-in
· Operating Temperature Range: -40°C ~ +85°C
Package:
· 1x MAX9814 Microphone AGC Amplifier Module
