LM124JAN Datasheet | National Semiconductor

Description The LM124/124A consists of four independent, high gain, internally frequency pensated operational amplifiers which were designed specifically 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 LM124/124A can be directly operated off of the standard +5Vdc power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional +15Vdc power supplies. Unique Characteristics - In the linear mode the input mon-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage - The unity gain cross frequency is temperature pensated - The input bias current is also temperature pensated Advantages - Eliminates need for dual supplies - Four internally pensated op amps in a single package - Allows directly sensing near GND and VOUT also goes to - patible with all forms of logic - Power drain suitable for battery operation Features - Internally frequency pensated for unity gain - Large DC voltage gain 100 d B - Wide bandwidth (unity gain) 1 MHz (temperature pensated) - Wide power supply range: Single supply 3V to 32V or dual supplies ±1.5V to ±16V - Very low supply current drain (700 μA)- essentially independent of supply voltage - Low input biasing current 45 n A (temperature pensated) - Low input offset voltage 2 m V and offset current: 5 n A - Input mon-mode voltage range includes ground - Differential input voltage range equal to the power supply voltage - Large output voltage swing 0V to V+ - 1.5V Ordering Information NSC Part Number JL124BCA...
