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 industrystandard 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 (...
