LMV831/LMV832/LMV834

3 MHz Low Power CMOS, EMI Hardened Operational

Amplifiers

General Description

Features

National’s LMV831, LMV832, and LMV834 are CMOS input,

low power op amp IC's, providing a low input bias current, a

wide temperature range of −40°C to 125°C and exceptional

performance making them robust general purpose parts. Ad-

ditionally, the LMV831/LMV832/LMV834 are EMI hardened

to minimize any interference so they are ideal for EMI sensi-

tive applications.

Unless otherwise noted, typical values at T_A= 25°C,

The unity gain stable LMV831/LMV832/LMV834 feature

3.3 MHz of bandwidth while consuming only 0.24 mA of cur-

rent per channel. These parts also maintain stability for ca-

pacitive loads as large as 200 pF. The LMV831/LMV832/

LMV834 provide superior performance and economy in terms

of power and space usage.

Operating ambient temperature range −40°C to 125°C

This family of parts has a maximum input offset voltage of

1 mV, a rail-to-rail output stage and an input common-mode

voltage range that includes ground. Over an operating range Applications

from 2.7V to 5.5V the LMV831/LMV832/LMV834 provide a

PSRR of 93 dB, and a CMRR of 91 dB. The LMV831 is offered

in the space saving 5-Pin SC70 package, the LMV832 in the

8-Pin MSOP and the LMV834 is offered in the 14-Pin TSSOP

package.
