OPERATING VOLTAGE

The INA826 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 of this data sheet.

Low-Voltage Operation

The INA826 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

internal nodes limit the input common-mode range with low power-supply voltage. The typical characteristic

curves Typical Common-Mode Range vs Output Voltage (Figure 9 to Figure 16) and Offset Voltage vs Common-

Mode Voltage (Figure 41 to Figure 44) describe the range of linear operation 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 INA826 that have improved specifications in

critical areas that impact the precision of the overall system. Figure 63 shows an example application.
