说明

The INA333 is a low-power, precision instrumentationamplifier offering excellent accuracy. The versatile 3-op amp 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 + (100kΩ/R_G).

The INA333 provides very low offset voltage (25µV, G ≥ 100), excellent offset voltage drift (0.1µV/°C, 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 50µA—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.
