The MAX9814ETD+ from Analog Devices is a Class AB microphone preamplifier featuring Automatic Gain Control (AGC) and low-noise microphone bias. This component is designed for audio applications requiring high performance and reliability.
Key electrical specifications include a supply voltage range of 2.7V to 5.5V, making it versatile for various power-constrained designs. The device offers a typical Total Harmonic Distortion plus Noise (THD+N) of 0.04% at 10 kOhms load impedance and a VDD of 3.3V. It supports a load impedance range from 50 Ohms up to 500 Ohms and operates as a single-channel amplifier.
Packaged in a TDFN surface-mount case, the MAX9814ETD+ is suitable for automated assembly processes. It operates reliably within a temperature range of -40 C to 85 C, ensuring performance across diverse environmental conditions. The component is identified by its base number 9814 and has 14 pins.
This microphone preamplifier is ideal for applications where clear audio capture and signal amplification are critical. Its combination of AGC, low noise, and a wide operating voltage makes it a robust choice for audio front-ends in consumer electronics, communication devices, and embedded systems.
