What Stands Out

Auto Gain Control
The MAX9814 module intelligently adjusts its gain levels automatically, ensuring optimal audio capture in varying environments, which eliminates the need for manual adjustments.
Easy Integration
Designed for seamless compatibility with Arduino, this microphone amplifier module simplifies the process of adding high-quality audio input to projects, making it accessible for hobbyists and developers alike.
Compact Design
The small form factor of the DollaTek MAX9814 module allows for easy incorporation into space-constrained projects, ensuring that users can enhance their devices without sacrificing design or functionality.

Shop DollaTek MAX9814 Electret MIC Microphone Amplifier Module Auto Gain Control for Arduino online at a best price in Mongolia. B07DJWQDQF
  • The MAX9814 is a high-quality microphone amplifier with automatic gain control (AGC) and low-noise microphone bias. The device features a low-noise preamplifier, variable gain amplifier (VGA), output amplifier, microphone-bias-voltage generator and AGC control circuitry.
  • The low-noise preamplifier has a fixed 12dB gain, while the VGA gain automatically adjusts from 20dB to 0dB, depending on the output voltage and the AGC threshold. The output amplifier offers selectable gains of 8dB, 18dB, and 28dB. With no compression, the cascade of the amplifiers results in an overall gain of 40dB, 50dB, or 60dB.
  • A trilevel digital input programs the output amplifier gain. An external resistive divider controls the AGC threshold and a single capacitor programs the attack/release times.
  • A trilevel digital input programs the ratio of attack-to-release time. The hold time of the AGC is fixed at 30ms. The low-noise microphone-bias-voltage generator can bias most electret microphones.
  • The MAX9814 is available in the space-saving, 14-pin TDFN package. This device is specified over the -40°C to +85°C extended temperature range. MAX9814: Simplified Block Diagram MAX9814: Simplified Block Diagram Enlarge+

DollaTek Preamps Editorial Review

The DollaTek MAX9814 Electret Microphone Amplifier Module has garnered a mix of reviews that highlight its functionality, performance, and several caveats. Users appreciate its capability to provide high gain amplification, making it especially useful for applications where clear audio output is critical. One reviewer noted its effectiveness in their setup, achieving a notable 40dB increase in amplification, which contributes to its reputation as a solid choice for audio projects. While many users find the performance of the amplifier satisfying, especially for speech applications, some have expressed concerns regarding its auto gain control (AGC) feature. There are mentions of significant noise output when the AGC activates, particularly when dealing with weak sound signals. This could be a limiting factor for users working in quieter environments, as the undesirable noise can overshadow the desired audio. The size and design of the module are praised, including its integration capabilities with various microcontrollers like Arduino and Raspberry Pi. However, some customers have pointed out a lack of technical documentation online. They believe that having a comprehensive guide explaining all functions, especially the AGC, would enhance the user experience significantly. The absence of vital components, such as an output capacitor, has also been noted, leading users to take additional steps in their setups. Despite these drawbacks, the overall sentiment leans positively toward the DollaTek MAX9814, particularly for those who appreciate the potential of DIY audio projects. **
