LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers General Description The LM124 series consists of four independent, high gain, internally frequency compensated 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 sup- ply 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 sys- tems. For example, the LM124 series can be directly oper- ated off of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies. Unique Characteristics n In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage n The unity gain cross frequency is temperature compensated n The input bias current is also temperature compensated Advantages n Eliminates need for dual supplies n Four internally compensated op amps in a single package n Allows directly sensing near GND and V OUT also goes to GND n Compatible with all forms of logic n Power drain suitable for battery operation Features n Internally frequency compensated for unity gain n Large DC voltage gain 100 dB n Wide bandwidth (unity gain) 1 MHz (temperature compensated) n Wide power supply range: Single supply 3V to 32V or dual supplies ±1.5V to ±16V n Very low supply current drain (700 μA)—essentially independent of supply voltage n Low input biasing current 45 nA (temperature compensated) n Low input offset voltage 2 mV and offset current: 5 nA n Input common-mode voltage range includes ground n Differential input voltage range equal to the power supply voltage n Large output voltage swing 0V to V + - 1.5V Connection Diagram Note 1: LM124A available per JM38510/11006 Note 2: LM124 available per JM38510/11005 Dual-In-Line Package DS009299-1 Top View Order Number LM124J, LM124AJ, LM124J/883 (Note 2) , LM124AJ/883 (Note 1) , LM224J, LM224AJ, LM324J, LM324M, LM324MX, LM324AM, LM324AMX, LM2902M, LM2902MX, LM324N, LM324AN, LM324MT, LM324MTX or LM2902N LM124AJRQML and LM124AJRQMLV (Note 3) See NS Package Number J14A, M14A or N14A August 2000 LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers © 2000 National Semiconductor Corporation DS009299 www.national.com
