The 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 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/RG).

The INA333 provides very low offset voltage (25 µV at 25°C, G ≥ 100), excellent offset voltage drift (0.2 µV/°C, G ≥ 100), and high common-mode rejection (100 dB at 25°C, G ≥ 10). It operates with power supplies as low as 1.8 V (±0.9V), and quiescent current is only 50 µA—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 (55 nV/√Hz) that extends down to dc.

The INA333 is is specified over the TA = –55°C to +210°C temperature range.
