Features (Typical 1.8V Supply Values; Unless Otherwise Noted) Guaranteed 1.8V, 2.7V and 5V specifications Output swing w/600 load 80mV from rail w/2k load 30mV from rail VCM 200mV beyond rails Supply current (per channel) 100µA Gain bandwidth product 1.4MHz Maximum VOS 4.0mV Gain w/600 load 101dB Ultra tiny package micro SMD 1.0mm x 1.5mm Turn-on time from shutdown 19µs Temperature range -40°C to 125°C 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 common mode voltage extends 200mV beyond the supplies which enables user enhanced functionality beyond the supply voltage range. The output can swing rail-to-rail unloaded and within 105mV from the rail with 600 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. The output will be high impedance in shutdown. 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 600 load and up to 1000pF capacitive load with minimal ringing. LMV981/LMV982 have a high DC gain of 101dB, 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. Applications • Industrial and automotive • Consumer communication • Consumer computing • PDAs • Portable audio • Portable/battery-powered electronic equipment • Supply current monitoring • Battery monitoring

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
