Maxim MAX4063 Differential Microphone Preamplifier Datasheet
The MAX4063 is a differential‑input microphone preamplifier optimized for high‑performance portable applications. It offers selectable differential or single‑ended inputs, adjustable gain via a single external resistor, integrated low‑noise bias, and a low‑power shutdown mode that reduces supply current to 0.3 µA.
The device operates from 2.4 V to 5.5 V, is specified over –40 °C to +85 °C, and is available in 16‑pin thin QFN and 14‑pin TSSOP packages. Key performance figures include 95 dB PSRR, 79 dB CMRR, THD+N of 0.05 % at 1 kHz, and a full‑scale differential output of up to 6 V p‑p.
