BL3601 Nano-Power Operational Amplifier, Ultra-Low Power, Rail-to-Rail I/O, SOT23-5

The BL3601 is a single-channel nano-power operational amplifier specifically designed for ultra-low-power and battery-operated applications. Operating from a wide supply voltage range of 1.4V to 5.5V, it consumes only 550nA quiescent current per channel, making it ideal for energy-sensitive designs.
With a 10kHz gain bandwidth and 3.7V/ms slew rate, the BL3601 provides stable performance for low-frequency signal conditioning. Its rail-to-rail input and output capability ensures maximum signal swing even at low supply voltages. The compact SOT23-5 package allows easy integration into space-constrained portable systems.
