Milpitas, Calif. Linear Technology introduced the LT6703, a micropower comparator with a 400 mV voltage reference in a 2 x 2-mm package. The LT6703 operates with a supply voltage from 1.4 V to 18 V, making it suitable for low voltage or unregulated power supplies. The comparator requires 6.5µA of quiescent current and less than 10 nA of input bias current. With a total threshold error of 1.25%, the LT6703 is suited as a voltage monitor or threshold detector.
The input of the product can accept voltages from 0 to 18 V, independent of the supply voltage, and the open-collector output can be pulled up to 18 V, also independent of supply. This capability allows the LT6703 to interface to a range of signals or to serve as a voltage-level translator. Furthermore, it has built-in comparator hysteresis and a temperature range from -40°C to 125°C to aid operation in electrically noisy and high-temperature environments. Two versions provide the choice of input polarity; the LT6703-2 has the 400 mV reference connected to the non-inverting input and the LT6703-3 has the 400 mV reference connected to the inverting input.
