Typical Application


LM321/358/324 types consist of single/dual/quad channel independent, high gain, internally frequency compensated operational amplifiers which are designed specifically to operate from a single power supply over a wide range of voltages. They may also be operated from split power supplies. The supply current is basically independent of the supply voltage over the recommended voltage range.

These devices are particularly useful in interface circuits with digital systems and can be operated from the single common 5VDC power supply. They are also intended for transducer amplifiers, DC gain blocks and many other conventional op amp circuits which can benefit from the single power supply capability.

In the linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to both ground and power rail, even though operated from a single power supply.

The LM321 is single channel version available in 5-pin SOT23 packages. The LM358 is dual channel version available in 8-pin SOP, TSSOP and MSOP packages. The LM324 is quad channel version available in 14-pin SOP and TSSOP packages.
