Features Unless otherwise noted, typical values at TA = 25°C, V + = 5V. Space saving 5-Pin SC70 package Supply voltage range 2.7V to 12V Guaranteed at 3.3V, 5V and ±5V Low supply current 1mA per channel Unity gain bandwidth 4.5MHz Open loop gain 133dB Input offset voltage 500μV max Input bias current 0.3pA CMRR 112dB Input voltage noise 20nV/ √ ^Hz Temperature range −40°C to 125°C Rail-to-Rail input Rail-to-Rail output The LMV841Q, LMV842Q, and LMV844Q are AEC-Q100 grade 1 qualified and are manufactured on automotive grade flow. Description The LMV841/LMV842/LMV844 are low-voltage and low-power operational amplifiers that operate with supply voltages ranging from 2.7V to 12V and have rail-to-rail input and output capability. Their low offset voltage, low supply current, and MOS inputs make them ideal for sensor interface and battery-powered applications. The single LMV841 is offered in the space-saving 5-Pin SC70 package, the dual LMV842 in the 8-Pin MSOP and 8-Pin SOIC packages, and the quad LMV844 in the 14-Pin TSSOP and 14-Pin SOIC packages. These small packages are ideal solutions for area-constrained PC boards and portable electronics. The LMV841Q, LMV842Q, and LMV844Q incorporate enhanced manufacturing and support processes for the automotive market , including defect detection methodologies. Reliability qualification is compliant with the requirements and temperature grades defined in the AEC-Q100 standard. Applications High impedance sensor interface Battery powered instrumentation High gain amplifiers DAC buffer Instrumentation amplifiers Active filters

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.
