(Test Circuits 2 through 4)
THE CHARGE BALANCING CIRCUITRY SAMPLES THE VOLTAGE
AT S3 WITH RESPECT TO S4 (PIN 16 HIGH) AND INJECTS A
SMALL CHARGE AT THE C
THIS BOOSTS THE CMRR WHEN THE LTC1043 IS USED AS AN
INSTRUMENTATION AMPLIFIER FRONT END.
FOR MINIMUM CHARGE INJECTION IN OTHER TYPES OF
APPLICATIONS, S3A AND S3B SHOULD BE GROUNDED
