Descriptions:
The INA333 device is a low-power, precision instrumentation amplifier offering excellent accuracy. The versatile 3-operational amplifier design, small size, and low power make it ideal for a wide range of portable applications.
A single external resistor sets any gain from 1 to 1000. The INA333 is designed to use an industry-standard gain equation: G=1+(100kohm/RG).
The INA333 device provides very low offset voltage (25uV, G>=100), excellent offset voltage drift (0.1uV/℃, G>=100), and high common-mode rejection (100dB at G>=10). It operates with power supplies as low as 1.8V(+/-0.9V) and quiescent current is only 50uA, making it ideal for battery-operated systems. Using autocalibration techniques to ensure excellent precision over the extended industrial temperature range, the INA333 device also offers exceptionally low noise density (50nV/√Hz) that extends down to DC.
The INA333 device is available in both 8-pin VSSOP and WSON surface-mount packages and is specified over the TA =-40℃ to +125℃ temperature range
