Description

GY-MAX9814 microphone amplifier module MIC microphone sound amplification/microphone head sensor module

Package Condition
original

Product Descriptions

GY-MAX9814 is a low-cost high-performance microphone amplifier with automatic gain control (AGC) and low noise microphone bias. The 

device features a low-noise front-end amplifier, variable gain amplifier (VGA), output amplifier, microphone bias voltage generator, and AGC 

control circuit

Product Parameters

Automatic Gain Control (AGC)

3 gain settings (40dB, 50dB, 60dB)

Programmable action time

Programmable action to release time ratio

Power supply voltage range 2.7V~5.5V

Low THD: 0.04% (typical value)

Low power shutdown mode

Built in 2V low noise microphone bias

Product Pin Description

VCC: Power supply positive

GND: Ground

GAIN: Tri state amplifier gain control:

GAIN=VDD, set gain to 40dB

GAIN=GND, set gain to 50dB

GAIN=airborne, gain set to 60dB

OUT: amplifier output

AR: Three state start and release ratio selection, controlling the start time and release time ratio of the AGC circuit:

A/R=GND: Start/release ratio is 1:500

A/R=VDD: Start/release ratio is 1:2000

A/R=airborne: start/release ratio of 1:4000
