LMV982中文资料Low Power Operational Amplifier with Shutdown and Rail to Rail I/O数据手册ONSEMI规格书

描述 Description

The LMV981 Single and LMV982 Dual are CMOS low-voltage op-amps which can operate on single-sided power supplies (1.8 V to 5.0 V) with rail-to-rail input and output swing. Both devices come in small state-of-the-art packages and require very low quiescent current making them ideal for battery-operated, portable applications such as notebook computers and hand-held instruments. Rail-to-Rail operation provides improved signal-to-noise performance plus the small packages allow for closer placement to signal sources thereby reducing noise pickup. The single LMV931 is offered in space saving SC70-5 package. The dual LMV932 is in a Micro8. These small packages are very beneficial for crowded PCBs. Further reduction of power consumption is available with the addition of a shutdown function in the LMV981 Single and LMV982 Dual. All other functions and performance are the same as the LMV931/932. Shutdown is implemented by driving the SHDN pin LOW.
