General Description
The TC7650 CMOS chopper stabilized operational
amplifier practically removes offset voltage error terms
from system error calculations. The 5
V 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 elimi-
nates VOS trim procedures, periodic potentiometer
adjustment and the reliability problems caused by dam-
aged trimmers.
The TC7650 performance advantages are achieved
without the additional manufacturing complexity and
cost incurred with laser or "zener zap" VOS trim tech-
niques.
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.
