3 Description

The LMC6484 device providesa common-mode

range thatextends toboth supplyrails.Thisrail-to-rail

performance combined with excellent accuracy,due

toa highCMRR, makes this device unique among

rail-to-rail inputampliers.

The LMC6484 is an excellent choice for systems,

such as data acquisition, thatrequire a large input

signal range. Thedevice isalsoan excellentupgrade

for circuits usinglimited common-mode range

ampliers, suchas theand.TLC274 TLC279

Maximum dynamic signal range is maintained in low

voltage and single-supply systemsbythe rail-to-rail

output swing of the LMC6484. The rail-to-rail output

swing of the LMC6484 is specied for loads down to

600 .Ω

Specied low voltage characteristicsand low power

dissipation make the LMC6484 anexcellent choice

for battery-operatedsystems.
