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.

NOTES: (1) The internal gain set resistors have an absolute tolerance of ±20%; however, their tracking is 50ppm/°C. RG will add to the gain error if gains other than
1, 10, 100, or 1000 are set externally. (2) At high temperature, output drive current is limited. An external buffer can be used if required. (3) Adjustable to zero.
