TC514

The TC514 family is a precision analog front end dual slope A/D converter having a maximum resolution of 17 bits plus sign. The device contains the integrator, zero crossing comparator and processor interface logic. The TC514 has improved linearity allowing it to operate to a maximum resolution of 17 bits and adds both a negative power supply converter and a 4 input differential analog multiplexer. The TC514 offers superior 50Hz/60Hz noise rejection, low power operation, minimum I/O connections, and low input bias currents.
