SGM8042
670nA, Dual Rail-to-Rail I/O
Operational Amplifier
PRODUCT DESCRIPTION
The SGM8042 is guaranteed to operate with a single
supply voltage as low as 1.4V, while drawing less than
670nA (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 SGM8042 has a gain-bandwidth product of 14.5kHz
(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 SGM8042 is offered in dual configuration. It is
specified for the extended industrial (-40℃ to +85℃)
temperature range. The SGM8042 is available in the
Green SOIC-8 and MSOP-8 packages.
