TLH9299 LM124LM224LM324LM2902 Low Power Quad Operational Amplifiers December 1994 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 operat- ed off of the standard a5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional g15V power supplies Unique Characteristics Y 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 sin- gle power supply voltage Y The unity gain cross frequency is temperature compensated Y The input bias current is also temperature compensated Advantages Y Eliminates need for dual supplies Y Four internally compensated op amps in a single package Y Allows directly sensing near GND and V OUT also goes to GND Y Compatible with all forms of logic Y Power drain suitable for battery operation Features Y Internally frequency compensated for unity gain Y Large DC voltage gain 100 dB Y Wide bandwidth (unity gain) 1 MHz (temperature compensated) Y Wide power supply range Single supply 3V to 32V or dual supplies g15V to g16V Y Very low supply current drain (700 mA)essentially in- dependent of supply voltage Y Low input biasing current 45 nA (temperature compensated) Y Low input offset voltage 2 mV and offset current 5 nA Y Input common-mode voltage range includes ground Y Differential input voltage range equal to the power sup- ply voltage Y Large output voltage swing 0V to V a b 15V Connection Diagram Dual-In-Line Package TLH9299 – 1 Top View Order Number LM124J LM124AJ LM124J883 LM124AJ883 LM224J LM224AJ LM324J LM324M LM324AM LM2902M LM324N LM324AN or LM2902N See NS Package Number J14A M14A or N14A TLH9299 – 32 Order Number LM124AE883 or LM124E883 See NS Package Number E20A TLH9299 – 33 Order Number LM124AW883 or LM124W883 See NS Package Number W14B LM124A available per JM3851011006 LM124 available per JM3851011005 C1995 National Semiconductor Corporation RRD-B30M115Printed in U S A
