SGM8581
Single-Supply, Single Rail-to-Rail I/O
Precision Operational Amplifier
PRODUCT DESCRIPTION
The SGM8581 is a single 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
SGM8581 make both high-side and low-side sensing
easy. The combination of characteristics makes the
SGM8581 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 SGM8581 is specified for the extended industrial/
automotive (-40to +125℃) temperature range. The
SGM8581 is available in the Green SOT-23-5, SOIC-8
and MSOP-8 packages.
