The TC500 is a precision analog front end dual slope A/D converter having a maximum resolution of 16 bits plus sign. The device contains the integrator, zero crossing comparator and processor interface logic, and requires both positive and negative power supplies. The TC500 offers high resolution (up to 16 bits), superior 50Hz/60Hz noise rejection, low power operation, minimum I/O connections, and low input bias currents.
