Giới thiệu Mô đun khuếch đại có thể điều chỉnh Electret MAX -66 MAX4466 tại Lotte Market

Introduction:
The MAX4466 is a micropower operational amplifier optimized for use as a microphone preamplifier. They offer an ideal combination of optimized gain-bandwidth products and supply current, as well as low-voltage operation in ultra-small packages. The MAX4466 has gain stability and provides a gain bandwidth of 200kHz with only 24μA supply current. After decompression, a minimum 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 preamps, portable computers, speech recognition systems.

Features and benefits:
Power supply voltage: + 2.4V to + 5.5V (can be directly connected to STM / ARDUNIO / Raspberry Pi and other development board)

Power supply rejection ratio: 112dB

Common mode rejection ratio: 126dB
