GENERAL DESCRIPTION
The TC7650 CMOS chopper-stabilized operational amplifier practically removes offset voltage error terms from system error calculations. The 5µV maximum VOS specification, for example, represents a 15 times improvement over the industry-standard OP07E. The 50nV/°C offset drift specification is over 25 times lower than the OP07E. The increased performance eliminates VOS trim procedures, periodic potentiometer adjustment and the reliability problems caused by damaged trimmers.
