DESIGN FEATURES Low Noise, Micropower Precision Op
Amp Swings Outputs from Rail to Rail
by Kris Lokere and Glen Brisebois Introduction for the LT6011), the requirement to
stay 1V away from either rail leaves
less than 1V for the sensor signal, severely reducing the dynamic range. The
LT6011 allows the outputs to swing
to 40mV from either supply rail, making it practical in low supply voltage
applications.
In portable instrumentation, medical applications, or in sophisticated
systems that measure hundreds or
even thousands of variables simultaneously, the power consumption
of the precision op amp is important.
This is especially so because designers
usually want to burn as much of the
available power in the sensor itself,
since this tends to reduce noise. The
LT6011 suits all these applications
because the supply current is less
than 150ВµA per amplifierвЂ”instead
of the milliamps of other precision
amplifiers. In addition, micropower
operation has the obvious benefits
of increasing battery run time and …
