描述 Description

LM321/358/324 types consist of single/dual/quadchannel independent, high gain, internally frequencycompensated operational amplifiers which aredesigned specifically to operate from a single powersupply over a wide range of voltages.?

They may alsobe operated from split power supplies. The supplycurrent is basically independent of the supplyvoltage over the recommended voltage range.

These devices are particularly useful in interfacecircuits with digital systems and can be operatedfrom the single common 5VDC power supply.

Theyare also intended for transducer amplifiers, DC gainblocks and many other conventional op amp circuitswhich can benefit from the single power supplycapability.In the linear mode, the input common-mode voltagerange includes ground and the output voltage canalso swing to both ground and power rail, eventhough operated from a single power supply.

The LM321 is single channel version available in5-pin SOT23 packages. The LM358 is dual channelversion available in 8-pin SOP and MSOP packages.The LM324 is quad channel version available in14-pin SOP and TSSOP packages.
