The LT0 is optimized for lowest operating power while the LT0 operates at higher power and higher speed. Both devices can operate from a single.v cell up to 0V. The output stage includes a class B pullup current source, eliminating the need for an external resistive pull-up and saving power. The output stage is also designed to allow driving loads connected to a supply more positive than the device, as can comparators with open-collector output stages. Input specifications are also excellent. On-chip trimming minimizes offset voltage, while high gain and common mode rejection ratio keep other input referred errors low. Common mode voltage range includes ground. Special circuitry prevents false output states even if the input is overdriven. The LT0/LT0 are pin compatible with older dual comparators such as 9 type devices., LTC and LT are registered trademarks of Linear Technology Corporation.
