DESCRIPTION
The INA145 is a precision, unity-gain difference
amplifier consisting of a precision op amp and on-
chip precision resistor network. Two external resistors
set the gain from 1V/V to 1000V/V. The input com-
mon-mode voltage range extends beyond the positive
and negative rails.
On-chip precision resistors are laser-trimmed to achieve
accurate gain and high common-mode rejection. Ex-
cellent TCR tracking of these resistors assures contin-
ued high precision over temperature.
The INA145 is available in the SO-8 surface-mount
package specified for the extended industrial tempera-
ture range, –40°C to +85°C.
