Add To BomMAX9814ETD+T General Description
The MAX9814ETD+T is a low-power, high-performance microphone preamplifier with automatic gain control (AGC) and a digital microphone bias voltage generator. It is designed for applications requiring a high-quality microphone input, such as smartphones, tablets, and wearable devices. This preamplifier features a 2.7V to 3.63V operating voltage range and a low 0.75mA supply current, making it suitable for battery-operated devices. The AGC feature ensures consistent audio levels even in noisy environments, while the digital microphone bias voltage generator simplifies the design process by eliminating the need for external components.The MAX9814ETD+T comes in a tiny 14-pin TDFN package, making it easy to integrate into small, space-constrained designs. It also has a high 78dBPSR (power-supply rejection ratio) and a 20Hz to 20kHz bandwidth, ensuring clear and accurate audio capture.
