Linear Technology’ LT6703 is a micropower comparator with an integrated 400mV voltage reference in a tiny 2 x 2mm package. It operates with a supply voltage from 1.4 to 18V, which is ideal for low voltage or unregulated power supplies. It requires only 6.5uA of quiescent current and less than 10nA of input bias current. With a total threshold error of only 1.25%, the LT6703 is well suited as a voltage monitor or threshold detector.
In addition to its size and precision, the LT6703 is a very robust part. The input can accept voltages from 0 to 18V, independent of the supply voltage, and the open collector output can be pulled up to 18V, also independent of supply. This Over-The-Top capability allows the LT6703 to interface to a wide range of signals or to serve as a voltage level translator. Furthermore, the LT6703 has built-in comparator hysteresis and guaranteed specifications from -40°C to 125°C to ensure reliable operation in electrically noisy and high temperature environments.
