(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied.
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3V beyond the supply rails should be current limited to 10mA or less.
(3) Short-circuit to ground.DescriptionThe INA333 is a low-power, precision instrumentation amplifier offering excellent accuracy. The versatile 3-op amp design, small size, and low power make it ideal for a wide range of protable applications.
A single external resistor sets any gain from 1 to 1000.The INA333 is designed to uwee an industry-standard gain equation: G = 1 + (100k/RG).
The INA333 provides very low offset voltage (25V, G 100), excellent offset voltage drift G 100), and high common-mode rejection (100dB(0.1V/,G 100), and high common-mode rejection (100dB at G10). It operates with power supplies as 1.8V (±0.9V), and quiescent current is only 50A-ideal for battery-operated systems. Using autocalibration techniques to ensure excellent precision over the extended industrial temperature range, the INA333 also offers exceptionally low noise density (50nV/Hz) that extends down to dc.
The INA333 is available in both MSOP-8 and DFN-8 surface-mount packages and is specified over the TA = 40 to +125 temperature range.
