Product Introduction
The MAX4466 are micropower operational amplifiers optimized for use as microphone preamplifiers. They offer an ideal combination of optimized gain-bandwidth product and supply current, as well as low-voltage operation in an ultra-small package. The MAX4466 is gain-stable and provides a gain-bandwidth of 200kHz with only 24μA of 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, making them suitable for operation in noisy environments. They are widely used in cellular phones, digital repeaters, headphones, hearing aids, microphone preamplifiers, portable computers, and speech recognition systems.
