January 25, 2008 LMV341/LMV342/LMV344 Single with Shutdown/Dual/Quad General Purpose, 2.7V, Rail-to-Rail Output, 125°C, Operational Amplifiers General Description The LMV341/LMV342/LMV344 are single, dual, and quad low voltage, low power Operational Amplifiers. They are designed specifically for low voltage portable applications. Other im- portant 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 off- set 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 al- lows the LMV341/LMV342/LMV344 to accommodate a broad range of extended environment applications. LMV341 ex- pands National Semiconductor's Silicon Dust™ amplifier port- folio 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 re- duced to 45pA (typical). The LMV341/LMV342/LMV344 have 29nV Voltage Noise at 10KHz, 1MHz GBW, 1.0V/ μs Slew Rate, 0.25mVos, and 0.1μA 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 con- strained PC board requirements include portable electronics such as cellular handsets and PDAs.

Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics. Field-Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC). Note 3: Shorting output to V+ will adversely affect reliability. Note 4: Shorting output to V- will adversely affect reliability. Note 5: The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA)/ θJA. All numbers apply for packages soldered directly onto a PC Board. Note 6: Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material. Note 7: All limits are guaranteed by testing or statistical analysis. Note 8: RL is connected to mid-supply. The output voltage is GND + 0.2V ≤ VO ≤ V+ −0.2V Note 9: Connected as voltage follower with 2VPP step input. Number specified is the slower of the positive and negative slew rates. Note 10: Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self heating where TJ > TA. www.national.com 4 LMV341/LMV342/LMV344
