Description
The LMV321 (single), LMV358 (dual), and LMV324 (quad)
are a low cost, voltage feedback amplifiers that consume only
80µA of supply current per amplifier. The LMV3XX family
is designed to operate from 2.7V (±1.35V) to 5.5V (±2.75V)
supplies. The common mode voltage 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 1.2MHz of bandwidth and 1.5V/µs of slew rate at a
low supply voltage of 2.7V. The combination of low power,
rail-to-rail performance, low voltage operation, 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 battery powered applications.
