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.

模拟工程师计算器旨在加快模拟电路设计工程师经常使用的许多重复性计算。该基于 PC 的工具提供图形界面,其中显示各种常见计算的列表(从使用反馈电阻器设置运算放大器增益到为稳定模数转换器 (ADC) 驱动器缓冲器电路选择合适的电路设计元件)。除了可用作单独的工具之外,该计算器还能够很好地与模拟工程师口袋参考书中所述的概念配合使用。
设计工具

CIRCUIT060013 — 采用 T 网络反馈电路的反相放大器

该设计将输入信号 VIN 反相并应用 1000V/V 或 60dB 的信号增益。具有 T 反馈网络的反相放大器可用于获得高增益,而无需 R4 具有很小的值或反馈电阻器具有很大的值。
设计工具

CIRCUIT060015 — 可调节基准电压电路

该电路结合了一个反相和同相放大器,可使基准电压在正负输入电压范围内进行调节。可通过增加增益来提高最大负基准电压电平。
设计工具

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。
