SOT-23 Micropower, Rail-to-Rail Op Amps Operate with Inputs
Above the Positive Supply вЂ“ Design Note 221
Raj Ramchandani
Introduction
The only SOT-23 op amps featuring Over-The-Top В® operationвЂ”the ability to operate with either or both inputs above
the positive railвЂ”are the 55ВµA LTВ®1782 and the 300ВµA
LT1783. This feature is important in many current-sensing
applications, where the inputs are required to operate at
or above the supply. The wide supply voltage range, from
2.7V to 18V, gives the LT1782/LT1783 broad appeal as
general purpose amplifiers, while the guaranteed offset
voltage of 950ВµV over temperature is the lowest of any
SOT-23 op amp. There is even a shutdown feature for
ultralow supply current applications.
Tough General Purpose Op Amps
The LT1782/LT1783 SOT-23 op amps are ideal for general
purpose applications that demand excellent performance.
These SOT-23 op amps are specified at input common
mode voltages as high as 18V, independent of the supply
voltage, making them ideal for applications with a wide
input range requirement and/or unusual input conditions.
In applications that require more bandwidth than the
200kHz LT1782, the LT1783вЂ™s six-fold increase in supply …

Dual 25ВµV Micropower Op Amp Fits in 3mm Г— 3mm Package
Design Note 331
Glen Brisebois
Introduction
Conventional monolithic micropower op amps with a
wide supply voltage range require a large die area and
therefore, a large package and footprint. The unconventional LTВ®6011 dual op amp п¬Ѓts 25ОјV input precision
micropower operation and wide 2.7V to 36V supply range
in a tiny new packageвЂ”its 3mm Г— 3mm DFN package
is so small it doesnвЂ™t even have leads. The LT6011 also
provides rail-to-rail output swing and utilizes superbeta
input transistors to achieve picoampere input currents.
Hall Sensor Ampliп¬Ѓer
Figure 1 shows the LT6011 applied as a low power Hall
sensor ampliп¬Ѓer. The magnetic sensitivity of a Hall sensor is proportional to the DC excitation voltage applied
across it. With a 1V bias voltage, the sensitivity of this
Hall sensor is speciп¬Ѓed as 4mV/mTesla of magnetic
п¬Ѓeld. At that level of DC bias, however, the 400О© bridge
consumes 2.5mA. Reducing the excitation voltage would
reduce the power consumption, but it would also reduce
the sensitivity. This is where the beauty of precision
micropower ampliп¬Ѓcation becomes especially apparent.
The LT1790-1.25 micropower reference provides a …
