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.<\/p>\n

Drawing only 24uA supply current, it provides rail-to-rail outputs, 112dB PSRR, and 126dB CMRR for excellent noise rejection in portable audio applications. The tiny 5-pin SOT-23 package minimizes board space.","working_principle":"The MAX4466 is an op-amp optimized for microphone preamplification. The decompensated architecture extends bandwidth to 600kHz for gains of 5 or higher, compared to 200kHz for the unity-gain stable MAX4465. The rail-to-rail output stage maximizes dynamic range in low-voltage applications. The high PSRR (112dB) and CMRR (126dB) ensure clean audio output even in electrically noisy environments such as cellular phones.","pin_description":"
