MAXIM INTEGRATED / ANALOG DEVICES MAX40089AUA Ultra-Low Noise Amplifier

The MAX40089AUA are multi-channel ultra-low noise operational amplifiers designed for high-impedance, low-distortion, and rail-to-rail output applications. These amplifiers operate from a single supply voltage of 2.7V to 5.5V, with exceptionally low input bias current of 50fA and low voltage noise density of 4.2nV/VHz. Featuring bandwidths of 42MHz and stable for gains up to 5, they are ideal for medical instrumentation, transimpedance, and sensor signal conditioning where low noise and distortion are critical. Packages include 14-TSSOP and ultra-small WLP package options, with excellent thermal characteristics and ESD protection.
