The LM324AN is a quad independent high-gain frequency-compensated Operational Amplifier designed specifically to operate from a single supply or split supply over a wide range of voltages.
Internal frequency compensation
Common-mode input voltage range includes ground, allowing direct sensing near ground
0.8mA Typical low supply-current drain independent of supply voltage
2mV Typical input offset voltage
2nA Typical input offset current
15nA Typical input bias current
100V/mV Typical open-loop differential voltage amplification
