TC7650

TC7650 CMOS chopper-stabilized operational amplifier practically removes offset voltage error terms from system error calculations. 5uV maximum VOS specification, for example, represents a 15 times improvement over the industry-standard OP07E. 50 nV/°C off-set drift specification is over 25 times lower than the OP07E. Increased performance eliminates VOS trim procedures, periodic potentiometer adjustment and the reliability problems caused by damaged trimmers. The TC7650 performance advantages are achieved without the additional manufacturing complexity and cost incurred with laser or "zener zap" VOS trim techniques. The TC7650 nulling scheme corrects both DC VOS errors and VOS drift errors with temperature. A nulling amplifier alternately corrects its own VOS errors and the main amplifier VOS error. Offset nulling voltages are stored on two user-supplied external capacitors. The capacitors connect to the internal amplifier VOS null points. The main amplifier input signal is never switched. Switching spikes are not present at the TC7650 output. The 14-pin dual-in-line package (DIP) has an external oscillator input to drive the nulling circuitry for optimum noise performance. Both the 8 and 14-pin DIPs have an output voltage clamp circuit to minimize overload recovery time.
