SGM8141
380nA, Single Rail-to-Rail I/O
Operational Amplifier
PRODUCT DESCRIPTION
The SGM8141 is guaranteed to operate with a single
supply voltage as low as 1.4V, while drawing less than
380nA (TYP) of quiescent current. This device is also
designed to support rail-to-rail input and output operation.
This combination of features supports battery-powered
and portable applications.
The SGM8141 has a gain-bandwidth product of 5kHz
(TYP) and is unity gain stable. These specifications
make this operational amplifier appropriate for low
frequency applications, such as battery current
monitoring and sensor conditioning.
The SGM8141 is offered in single configuration. It is
specified for the extended industrial (-40℃ to +85℃)
temperature range. The SGM8141 is available in the
Green SOT-23-5, SOIC-8 and MSOP-8 packages.
