德州仪器推出LM124-SP四路运算放大器

LM124-SP四路运算放大器说明

这些设备包括四个独立的高增益频率补偿是专为工作在较广泛的电压单电源运算放大器。行动由分离电源也是可能的，如果两个电源之间的差额为3 V至32 V和VCC低于输入共模电压1.5伏，至少更积极。低电源电流消耗，是对供应电压的大小无关。

应用包括传感器放大器，直流放大块，和所有的传统运算放大器，现在可以更容易地在单电源电压系统实现电路。例如，LM124可以操作直接从标准的5 V电源，用于在数字系统，并提供所需的接口电子设备，而无需额外的± 15 V电源。

These devices consist of four independent high-gain frequency-compensated operational amplifiers that are designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage.

Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational-amplifier circuits that now can be more easily implemented in single-supply-voltage systems. For example, the LM124 can be operated directly from the standard 5-V supply that is used in digital systems and provides the required interface electronics, without requiring additional ±15-V supplies.
