SGM8584
Single-Supply, Quad Rail-to-Rail I/O
Precision Operational Amplifier
PRODUCT DESCRIPTION
The SGM8584 is a quad rail-to-rail input and output
precision operational amplifier which has low input offset
voltage, and bias current. It is guaranteed to operate
from 2.5V to 5.5V single supply.
The rail-to-rail input and output swings provided by the
SGM8584 make both high-side and low-side sensing
easy. The combination of characteristics makes the
SGM8584 good choices for temperature, position and
pressure sensors, medical equipment and strain gauge
amplifiers, or any other 2.5V to 5.5V application requiring
precision and long term stability.
The SGM8584 is specified for the extended industrial/
automotive (-40to +125) temperature range. The
SGM8584 comes in the Green SOIC-14 and TSSOP-14
packages.
