DescriptionThe LMV341/LMV342/LMV344 are single, dual, and quad low voltage, low power Operational Amplifiers. They are designed specifically for low voltage portable applications. Other important product characteristics are low input bias current, rail-to-rail output, and wide temperature range.
The patented class AB turnaround stage significantly reduces the noise at higher frequencies, power consumption, and offset voltage. The PMOS input stage provides the user with ultra-low input bias current of 20fA (typical) and high input impedance.
The industrial-plus temperature range of −40°C to 125°C allows the LMV341/LMV342/LMV344 to accommodate a broad range of extended environment applications. LMV341 expands National Semiconductor's Silicon Dust amplifier portfolio offering enhancements in size, speed, and power savings. The LMV341/LMV342/LMV344 are guaranteed to operate over the voltage range of 2.7V to 5.5V and all have rail-to-rail output.
The LMV341 offers a shutdown pin that can be used to disable the device. Once in shutdown mode, the supply current is reduced to 45pA (typical). The LMV341/LMV342/LMV344 have 29nV Voltage Noise at 10KHz, 1MHz GBW, 1.0V/s Slew Rate, 0.25mVos, and 0.1A shutdown current (LMV341.)
The LMV341 is offered in the tiny 6-Pin SC70 package, the LMV342 in space saving 8-Pin MSOP and SOIC, and the LMV344 in 14-Pin TSSOP and SOIC. These small package amplifiers offer an ideal solution for applications requiring minimum PC board footprint. Applications with area constrained PC board requirements include portable electronics such as cellular handsets and PDAs.

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.For more information on Reliability Metrics, please click here.
