The UC3704 is an integrated circuit that contains a complete signal conditioning system for interfacing low-level variable impedance transducers to a digital system. A pair of matched, temperature-compensated current sources are provided for balanced transducer excitation followed by a precision, high-gain comparator. The output of this comparator can be delayed by a user-selectable duration, after which a second comparator will switch complementary outputs separately activated for diagnostic operation and has an optional latch with external reset capability. An added feature is a high current power source useful as a heater driver in differential temperature sensing applications. The UC3704 is designed for 0°C to +70°C environments.
