MAXIM INTEGRATED / ANALOG DEVICES MAX4478AUDT Low-Noise Amplifier

The MAX4478 ultrasonic detector features ultra-low noise and distortion, ideal for high-precision instrumentation and sensor applications. Designed for single-supply operation from +2.7V to +5.5V, it provides rail-to-rail outputs and low input voltage noise density (4.5nV/√Hz). Its low quiescent current (2.2mA) and shutdown mode for power saving make it suitable for portable devices. This high-bandwidth, low-distortion operational amplifier excels in ADC buffers, medical systems, and noise-sensitive electronics, delivering reliable performance with minimal signal interference effectively.
