The LM124-N series consists of four independent, high-gain, internally frequency compensated operational amplifiers designed to operate from a single power supply over a wide range of voltages. Operation from split-power supplies is also possible and the low-power supply current drain is independent of the magnitude of the power supply voltage.

Application areas include transducer amplifiers, DC gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM124-N series can directly operate off of the standard 5-V power supply voltage which is used in digital systems and easily provides the required interface electronics without requiring the additional ±15 V power supplies.

CIRCUIT060074 — 采用比较器的高侧电流检测电路

该高侧电流检测解决方案使用一个具有轨到轨输入共模范围的比较器，如果负载电流上升至超过 1A，则在比较器输出端 (COMP OUT) 产生过流警报 (OC-Alert) 信号。该实现中的 OC-Alert 信号低电平有效。因此，当超过 1A 阈值后，比较器输出变为低电平。实现了迟滞，使得当负载电流减小至 0.5 A（减少 50%）时，OC-Alert 将返回到逻辑高电平状态。该电路使用漏极开路输出比较器，从而对输出高逻辑电平进行电平转换，以控制数字逻辑输入引脚。对于需要驱动 MOSFET 开关栅极的应用，最好使用具有推挽输出的比较器。
