LMV841/LMV842/LMV842Q/

LMV844/LMV844Q

CMOS Input, RRIO, Wide Supply Range Operational

Amplifiers

General Description

Features

The LMV841/LMV842/LMV844 are low-voltage and low-pow-

er 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.

Unless otherwise noted, typical values at T_A= 25°C, V⁺= 5V.

Space saving 5-Pin SC70 package

Supply voltage range 2.7V to 12V

Guaranteed at 3.3V, 5V and ±5V

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 elec-

tronics.

The LMV842Q and LMV844Q incorporate enhanced manu-

facturing and support processes for the automotive market ,

including defect detection methodologies.

The LMV842Q and LMV844Q are AEC-Q100 grade 1

qualified and are manufactured on automotive grade

flow.

Reliability qualification is compliant with the requirements and

temperature grades defined in the AEC-Q100 standard.
