LM324 – Low Power Quad Operational Amplifier

Features


� Internally frequency compensated for unity gain
� Large DC voltage gain 100 dB
� Wide bandwidth (unity gain) 1 MHz (temperature compensated)
� Wide power supply range: Single supply 3V to 32V or dual supplies �1.5V to �16V
� Very low supply current drain (700 �A)-essentially independent of supply voltage
� Low input biasing current 45 nA (temperature compensated)
� Low input offset voltage 2 mV and offset current: 5 nA
� Input common-mode voltage range includes ground
� Differential input voltage range equal to the power supply voltage
� Large output voltage swing 0V to V+ – 1.5V

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
