BL3704 Quad Low Noise Operational Amplifier, 6.5nV/√Hz, SOP14 / TSSOP14

The BL3704 is a quad-channel low-noise operational amplifier integrating four precision amplifiers in a single package. With 6.5nV/√Hz noise density, it is ideal for multi-channel low-noise signal processing applications.
Operating from 2.1V to 5.5V, the BL3704 provides 12MHz bandwidth, 11V/µs slew rate, and rail-to-rail input/output, ensuring consistent performance across all channels. The SOP14 and TSSOP14 packages help reduce PCB space and component count.
