6Pcs Electret Microphone Amplifier Sound Sensor Module Compatible with MAX4466 for Arduino Raspberry Pi ESP32

Description

Model: Microphone Amplifier Sound Sensor Module Microphone Amplifier Sound Sensor Module are micropower operational amplifiers optimized for use as microphone preamplifiers. They provide an ideal combination of optimized gain-bandwidth product and supply current, as well as low-voltage operation in an ultra-small package. Microphone Amplifier Sound Sensor Module is gain-stable and provides a 200kHz gain-bandwidth with only 24μA supply current. After decompression, a small stable gain of +5V/V is achieved and a 600kHz gain-bandwidth product is provided. In addition, these amplifiers feature rail-to-rail output, high AVOL, and excellent power supply rejection and common-mode rejection ratio for operation in noisy environments. Widely used in cellular phones, digital repeaters, headphones, hearing aids, microphone preamplifiers, portable computers, and speech recognition systems. Power supply voltage: +2.4V to +5.5V (compatible with direct connection to STM/ARDUNIO/Raspberry Pi and other development boards) Power supply rejection ratio: 112dB Common mode rejection ratio: 126dB AVOL: 125dB (RL = 100kΩ) rail-to-rail output Quiescent supply current: <24μA Gain bandwidth: 600kHz Product includes: 6Pcs Microphone Amplifier Sound Sensor Module
