产品概览
The MAX4466EUK+T is a low-cost micropower microphone preamplifier from Analog Devices (formerly Maxim Integrated). It is a decompensated version optimized for minimum stable gain of +5V/V, providing a 600kHz gain bandwidth product from only 24uA supply current. The device features rail-to-rail outputs, excellent 112dB PSRR, and 126dB CMRR, making it ideal for audio signal conditioning in noisy environments.
