SGM8142
350nA, Dual Rail-to-Rail I/O
Operational Amplifier
 
PRODUCT DESCRIPTION
The SGM8142 is guaranteed to operate with a single
supply voltage as low as 1.4V, while drawing less than
350nA (TYP) of quiescent current per amplifier. 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 SGM8142 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 SGM8142 is offered in dual configuration. It is
specified for the extended industrial (-40
℃ to +85℃)
temperature range. The SGM8142 is available in the
Green SOIC-8 and MSOP-8 packages.
