LM124-SP四路運算放大器說明

這些設(shè)備包括四個獨立的高增益頻率補償是專為工作在較廣泛的電壓單電源運算放大器。行動由分離電源也是可能的，如果兩個電源之間的差額為3 V至32 V和VCC低于輸入共模電壓1.5伏，至少更積極。低電源電流消耗，是對供應(yīng)電壓的大小無關(guān)。

應(yīng)用包括傳感器放大器，直流放大塊，和所有的傳統(tǒng)運算放大器，現(xiàn)在可以更容易地在單電源電壓系統(tǒng)實現(xiàn)電路。例如，LM124可以操作直接從標準的5 V電源，用于在數(shù)字系統(tǒng)，并提供所需的接口電子設(shè)備，而無需額外的± 15 V電源。

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.
