BL3604 Nano-Power Operational Amplifier, Quad Channel, Ultra-Low Power, SOP14 / TSSOP14

The BL3604 is a quad-channel nano-power operational amplifier designed for high-density, ultra-low-power analog applications. Consuming only 550nA per channel, it is ideal for systems requiring multiple low-power amplification paths.
Operating from 1.4V to 5.5V, the BL3604 features rail-to-rail input and output, enabling full signal swing at low supply voltages. With a 10kHz gain bandwidth and 3.7V/ms slew rate, it delivers stable performance for low-frequency sensing and monitoring applications. The device is available in SOP14 and TSSOP14 packages, supporting compact multi-channel designs.
