BL3711 Low Power Low Noise Operational Amplifier, 12.5nV/√Hz, SOT23-5

The BL3711 is a single-channel low-power, low-noise operational amplifier designed for battery-powered and energy-efficient applications. It offers 12.5nV/√Hz noise density while consuming only 400µA quiescent current, making it ideal for low-power precision designs.
With 6MHz gain bandwidth, 8.5V/µs slew rate, and rail-to-rail input/output, the BL3711 operates reliably from 2.1V to 5.5V. Its compact SOT23-5 package supports high-density PCB layouts.
