LMV982
LMV982 is 1.8V / RRIO Operational Amplifiers manufactured by National Semiconductor.
- Part of the LMV comparator family.
- Part of the LMV comparator family.
Description
LMV981/LMV982 are low voltage, low power operational amplifiers. LMV981/LMV982 are guaranteed to operate from +1.8V to +5.0V supply voltages and have rail-to-rail input and output. LMV981/LMV982 input mon mode voltage extends 200m V beyond the supplies which enables user enhanced functionality beyond the supply voltage range. The output can swing rail-to-rail unloaded and within 105m V from the rail with 600Ω load at 1.8V supply. LMV981/ LMV982 are optimized to work at 1.8V which make them ideal for portable two-cell battery powered systems and single cell Li-Ion systems. LMV981/LMV982 offer a shutdown pin that can be used to disable the device and reduce the supply current. The device is in shutdown when the SHDN-pin = low. LMV981/LMV982 exhibit excellent speed-power ratio, achieving 1.4MHz gain bandwidth product at 1.8V supply voltage with very low supply current. LMV981/LMV982 are capable of driving a 600Ω load and up to 1000p F capacitive load with minimal ringing. LMV981/LMV982 have a high DC gain of 101d B, making them suitable for low frequency applications. LMV981 is offered in space saving 6-Bump micro SMD, SC70-6 and SOT23-6 packages. The 6-Bump micro SMD package has only a 1.006mm x 1.514mm x 0.945mm footprint. LMV982 is offered in space saving MSOP-10 package. These small packages are ideal solutions for area constrained PC boards and portable electronics such as cellular phones and PDAs.
