Introduction:
MAX4466 is a low-power operational amplifier that has been optimized and can be used as a microphone preamplifier. They provide an ideal combination of optimized gain bandwidth products and power supply currents, as well as low voltage operation in ultra small packages. MAX4466 has gain stability and can provide a gain bandwidth of 200kHz with only a power supply current of 24 μ A. After decompression, a minimum stable gain of+5V/V can be achieved, and a 600kHz gain bandwidth product can be provided. In addition, these amplifiers also have rail to rail output, high AVOL, and excellent power supply rejection and common mode rejection ratios, making them suitable for working in noisy environments. Widely used in cellular phones, digital repeating devices, headphones, hearing aids, microphone preamplifiers, portable computers, and speech recognition systems.
