INA333AIDRGR General Description

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 + (100 kΩ / RG).

The INA333 device provides very low offset voltage (25 µV, G ≥ 100), excellent offset voltage drift (0.1 µV/°C, G ≥ 100), and high common-mode rejection (100 dB at G ≥ 10). It operates with power supplies as low as 1.8 V (±0.9 V) and quiescent current is only 50 µA, 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 (50 nV/√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°C to +125°C temperature range.
