7.1 Overview

The INA333-Q1 is a monolithic instrumentation amplifier (INA) based on the precision zero-drift INA333-Q1 (operational amplifier) core. The INA333-Q1 also integrates laser-trimmed resistors to maintain excellent common-mode rejection and low gain error. The combination of the zero-drift amplifier core and the precision resistors allows this device to achieve outstanding dc precision, and makes the INA333-Q1 an excellent choice for many 3.3-V and 5-V automotive applications.
