Key Featrues
Low-Noise Microphone Bias: The internal low-noise microphone bias (2V) minimizes electrical noise, improving the signal-to-noise ratio (SNR). This results in cleaner audio capture, making it ideal for high-quality portable recorders, headsets, and other audio-sensitive applications.
Three Programmable Gain Settings (40dB, 50dB, 60dB): The device offers selectable gain levels, allowing users to optimize audio amplification for specific use cases. This flexibility improves efficiency and performance across a wide range of applications, from low-volume whispers to high-intensity sound sources.
Low Input-Referred Noise Density (30nV/√Hz): The amplifier's low noise density ensures minimal interference from internal circuitry, delivering high-fidelity audio. This feature is particularly beneficial for professional audio equipment, such as digital cameras and video recorders, where audio quality is critical.
Space-Saving 14-Pin TDFN Package (3mm × 3mm): The compact package design enables integration into small form-factor devices, such as Bluetooth headsets and PDAs. This reduces the overall footprint while maintaining high performance, making it suitable for portable and space-constrained applications.
Applications
Digital Still Cameras: The MAX9814 is perfect for capturing clear audio in digital still cameras. Its low input-referred noise density and programmable gain settings ensure high-quality sound recording, even in varying acoustic environments, enhancing the overall multimedia experience.
IP Phones/Telephone Conferencing: The MAX9814 is well-suited for IP phones and conferencing systems. Its AGC and low THD (Total Harmonic Distortion) ensure clear and stable audio output, making it ideal for professional communication systems where voice clarity is critical.
High-Quality Portable Recorders: The MAX9814 is excellent for portable audio recording devices. Its low-power shutdown mode and extended temperature range make it suitable for portable applications, while the internal low-noise microphone bias ensures high-fidelity audio capture in various recording environments.
