INA333AIDGKR Instrumentation Amplifier Lo Pwr Prec Inst Amp

Description

The INA333AIDGKR is a low-power, Precision Instrumentation Amplifier offers 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 INA333AIDGKR is designed to use an industry-standard gain equation - G = 1 + (100kR/RG). The INA333AIDGKR 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 auto calibration techniques to ensure excellent precision over the extended industrial temperature range, the INA333AIDGKR also offers exceptionally low noise density (50nV/√Hz) that extends down to DC.
