LMV981/LMV982 low-voltage, low-power operational amplifiers. The LMV981/LMV982 has a +1.8 V to +5.0 V supply voltage and rail-to-rail inputs and outputs. The LMV981/LMV982 input common mode voltage of 200mV is extended beyond the supply voltage range, allowing user enhancements to exceed the supply. Output swing rail-to-rail unloading and 600Ω load 105mV in 1.8V power rail. The LMV981/LMV982 is optimized to operate at 1.8V, making it ideal for portable dual-battery powered systems and single-cell lithium-ion battery systems.
The LMV981/LMV982 provides a stop pin that can be used to disable devices to reduce the supply current. ^ SHDN pin=low when the device is off. The output will be shut down with high impedance.
The LMV981/LMV982 have excellent high-speed power ratios, achieving extremely low supply current at 1.8V supply voltage and gain bandwidth of 1.4MHz. The LMV981/LMV982 is capable of driving 600Ω loads and capacitive loads up to 1000pF with a minimum ring. The LMV981/LMV982 has a high DC gain of 101 dB, making them suitable for low-frequency applications.
The LMV981 is available in a 6-bump micro SMD in SC70-6, SOT23-6 package space. 6-bump micro SMD package with a 1.006 mm x 1.514 mm x 0.945 mm footprint. The LMV982 is available in an energy-efficient MSOP-10 package. These small package areas are ideal for PC boards such as cellular phones and PDAs for portable electronics.
