Low Cost, Precision Difference Amplifiers
D
The
INA133
precision unity gain difference amplifier brings improved
performance to this versatile circuit building block. Its high
performance op amp and precision laser-trimmed resistors provide
excellent common-mode rejection and gain accuracy. Its output swing
to 1V of the rails and low quiescent current (1mA) are well-suited to
modern designs. A dual version,
INA2133
, saves space and lowers
cost.
A companion product, the
INA143
, provides a differential gain of 10
or 1/10. It can also be configured for single-input gains of +10, –10,
+11, or 1/10, and is also offered in a space-saving dual version, the
INA2143
.

High Voltage Difference Amplifiers
The
INA146
provides high common-mode voltage range—far beyond
its power supply rails. Its precision 10:1 feedback network divides
down input voltages, handling up to ±100V common-mode signals on
±12V supplies (or 40V common-mode on a single 5V supply). Gain
can be accurately programmed with external resistors. It’s great for
measuring voltages on current shunts!
The
INA145
has a unity-gain difference amp input stage with the same
resistor-programmed output gain. The INA145 and INA146 add a new
dimension to the versatility of the difference amp.

Low Power, Rail-to-Rail, Difference Amp
The
INA152
is a general purpose microsize difference amplifier
optimized for battery powered applications. It offers smallest size and
widest output swing of any difference amplifier.
Operating on power supplies as low as 2.7V at 450μA, with the ability
to swing to within 25mV of the power supply rails, the INA152 is an
excellent choice for battery–powered instrumentation applications.
It is available in a tiny MSOP-8 package.
