DIFFERENTIAL_INPUT_A_D_SYSTEM

Using a CA3140 BiMOS op amp provides good slewing capability for high bandwidth input signals, and can quickly settle energy that the CA3310 outputs at its VIN terminal. The CA3140 can also drive close to the negative supply rail. If system supply sequencing or an unknown input voltage is likely to cause the op amp to drive above the VDD supply, a diode clamp can be added from pin 8 of the op amp to the VDD supply.
