OPERATING VOLTAGE
The INA827 operates over a power-supply range of +2.7 V to +36 V (±1.35 V to ±18 V). Supply voltages higher
than 40 V (±20 V) can permanently damage the device. Parameters that vary over supply voltage or temperature
are shown in the Typical Characteristics section.
Low-Voltage Operation
The INA827 can operate on power supplies as low as ±1.35 V. Most parameters vary only slightly throughout this
supply voltage range; see the Typical Characteristics section. Operation at very low supply voltage requires
careful attention to assure that the input voltages remain within the linear range. Voltage swing requirements of
the internal nodes limit the input common-mode range with low power-supply voltage. Figure 7 to Figure 13 and
Figure 35 to Figure 38 describe the linear operation range for various supply voltages, reference connections,
and gains.
ERROR SOURCES
Most modern signal-conditioning systems calibrate errors at room temperature. However, calibration of errors
that result from a change in temperature is normally difficult and costly. Therefore, it is important to minimize
these errors by choosing high-precision components such as the INA827 that have improved specifications in
critical areas that impact overall system precision. Figure 59 shows an example application.
