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.

Input offset voltage 500μV max

Input bias current 0.3pA

CMRR 112dB

Input voltage noise 20nV/√Hz

Temperature range −40°C to 125°C

Rail-to-Rail input

The single LMV841 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 PC boards and portable

electronics.

Rail-to-Rail output

The LMV841Q, LMV842Q, and LMV844Q are

AEC-Q100 grade 1 qualified and are

manufactured on automotive grade flow.

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
