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.

    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.
