LMV841

CMOS 输入、RRIO、宽电源范围运算放大器

The LMV84x 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 is offered in the space-saving 5-Pin SC70 package, the dual LMV842 in the 8-Pin VSSOP 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 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.
