TC7652 LOW NOISE/ CHOPPER-STABILIZED OPERATIONAL AMPLIFIER

The TC7652 is a lower noise version of the TC7650, sacrificing some input specifications (bias current and bandwidth) to achieve a 10x reduction in noise. All the other benefits of the chopper technique are present, i.e. freedom from offset adjust, drift, and reliability problems from external trim .
