LM2902数据手册3PEAK中文资料规格书

描述 Description

LM2904/2902 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 LM2904 is dual channel version available in8-pin SOP and MSOP packages. The LM2902 isquad channel version available in 14-pin SOP andTSSOP packages.
