BL3892 Precision Operational Amplifier, Dual Channel, Low Offset, SOP8 / MSOP8

The BL3892 is a dual-channel precision operational amplifier offering high accuracy and low noise for multi-channel analog signal processing. With a maximum offset voltage of 38µV and 30nV/√Hz noise density, it ensures reliable performance in precision measurement applications.
Designed to operate from a 1.8V to 5.5V supply, the BL3892 features rail-to-rail input and output, making it ideal for low-voltage systems. Its 1.8MHz bandwidth and 0.95V/µs slew rate provide fast and stable response, while the SOP8 and MSOP8 packages offer flexibility for both standard and compact PCB layouts.
