The INA333 operates over a power-supply range of
+1.8V to +5.5V (±0.9V to ±2.75V). Supply voltages

vary over supply voltage or temperature are shown in
the Typical Characteristics section of this data sheet.
The INA333 can be operated on power supplies as
low as ±0.9V. 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.
