Description

The LMV321 (single), LMV358 (dual), and LMV324

(quad) are a low cost, voltage feedback amplifiers that

consume only 80

μA of supply current per amplifier. The

LMV3XX family is designed to operate from 2.7 V (±1.35

V) to 5.5 V (±2.75 V) supplies. The common mode volt-

age range extends below the negative rail and the output

provides rail-to-rail performance.

The LMV3XX family is designed on a CMOS process

and provides 1.2 MHz of bandwidth and 1.5 V/

μs of slew

rate at a low supply voltage of 2.7 V. The combination of

low power, rail-to-rail performance, low voltage opera-

tion, and tiny pack-age options make the LMV3XX family

well suited for use in personal electronics equipment

such as cellular handsets, pagers, PDAs, and other bat-

tery powered applications.
