3 Description

The LMV84x-Q1 devices are low-voltage and low-power operational amplifiers that operate with supply voltages ranging from 2.7 V to 12 V and have rail-to-rail input and output capability. Their low offset voltage, low supply current, and CMOS inputs make them ideal for high impedance sensor interface and battery-powered applications.

The single LMV841-Q1 is offered in the space-saving 5-pin SC70 package, the dual LMV842-Q1 in the 8-pin VSSOP and 8-pin SOIC packages, and the quad LMV844-Q1 in the 14-pin TSSOP and 14-pin SOIC packages. These small packages are ideal solutions for area-constrained PCBs and portable electronics.

The LMV841-Q1, LMV842-Q1, and LMV844-Q1 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.
