Description
The LMV321/358/324 family (single, dual and
quad) answers the need for low cost, general
purpose operational amplifiers. They operate with
voltages as low as 2.7 V and feature both input
and output rail-to-rail, 145 µA consumption
current and 1 MHz gain bandwidth product
(GBP).
With a such low consumption and a sufficient
GBP for many applications, these op-amps are
very well-suited for any kind of battery-supplied
and portable equipment application.
The LMV321 is housed in the space-saving 5-pin
SOT23-5 package which simplifies the board
design (overall dimensions are 2.8 mm x 2.9 mm).
The SOT23-5 has two pinning configurations to
answer all application requirements.
