The INA333 device is a low-power precision instrumentation amplifier with excellent accuracy. The device adopts a universal three-operational amplifier design, and has a small size and low power consumption characteristics, which is very suitable for various portable applications.
The gain can be set in the range of 1 to 1000 through a single external resistor. INA333 is designed to use an industry standard gain formula: G = 1 (100k/RG).
INA333 device has ultra-low offset voltage (25 μV, G≥ 100), excellent offset voltage drift (0.1 μV/°C, G≥ 100), and high common mode rejection ratio (100dB, G≥ 10).
Low offset voltage: 25 µV (maximum), G≥ 100, Low drift: 0.1 μV//°C, G ≥ 100, Low noise: 50nV/√Hz, G≥ 100, High common mode rejection ratio (CMRR):100dB (minimum), G≥ 10, Power range: 1.8V to 5.5V
Suitable for Bridge amplifier, Electrocardiogram (ECG) amplifier, Pressure sensor, Medical instrument, Portable instrument, Weighing instrument, Thermocouple amplifier , Resistance temperature detector (RTD) sensor amplifier, Data acquisition
