LMV841 Single/ LMV842 Dual/ LMV844 Quad CMOS Input, RRIO, Wide Supply Range Operational Amplifiers www.DataSheet4U.com October 2007 LMV841/LMV842/LMV844 CMOS Input, RRIO, Wide Supply Range Operational Amplifiers General 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 batterypowered 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. 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 1 mA per channel ■ Low supply current 4.5 MHz ■ Unity gain bandwidth 133 dB ■ Open loop gain 500 μV max ■ Input offset voltage 0.3 pA ■ Input bias current 112 dB ■ CMRR 20 nV/√Hz ■ Input voltage noise −40°C to 125°C ■ Temperature range ■ Rail-to-Rail input ■ Rail-to-Rail output Applications ■ ■ ■ ■ ■ ■ High impedance sensor interface Battery powered instrumentation High gain amplifiers DAC buffer Instrumentation amplifiers Active filters Typical Applications 20168301 © 2007 National Semiconductor Corporation 201683 www.national.com LMV841 Single/ LMV842 Dual/ LMV844 Quad www.DataSheet4U.com Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
