BL324 – High Voltage Quad General Operational Amplifier, 36V Supply, SOP14

The BL324 is a quad-channel high-voltage operational amplifier designed for multi-channel analog applications operating from elevated supply voltages. Supporting a 3.0V to 36V power range, it is ideal for industrial and automotive systems requiring multiple amplification stages.
The BL324 provides 1MHz gain bandwidth, 0.2V/µs slew rate, and low quiescent current of 250µA per channel, ensuring efficient and stable operation. With four amplifiers integrated into a single SOP14 package, it helps reduce component count and PCB area.
