FEATURES
DESCRIPTION
The INA102 is a high-accuracy monolithic instrumen-
tation amplifier designed for signal conditioning
applications where low quiescent power is desired.
On-chip thin-film resistors provide excellent tempera-
ture and stability performance. State-of-the-art laser-
trimming technology insures high gain accuracy and
common-mode rejection while avoiding expensive
external components. These features make the INA102
ideally suited for battery-powered and high-volume
applications.
The INA102 is also convenient to use. A gain of 1, 10,
100, or 1000 may be selected by simply strapping the
appropriate pins together. A gain drift of 5ppm/ C in
low gains can then be achieved without external
adjustment. When higher-than-specified CMR is
required, CMR can be trimmed using the pins pro-
vided. In addition, balanced filtering can be accom-
plished in the output stage.
