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.

Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality
levels are determined from tested parameters.
Notes:
3. Guaranteed by testing or statistical analysis at +25°C.
4. +IN and -IN are gates to CMOS transistors with typical input bias current of <1 nA. CMOS leakage is too small to
practically measure.
