Product Summary

The A5191HRTL is a single-chip, CMOS modem for use in Highway Addressable Remote Transducer (HART) field instruments and masters. The A5191HRTL and a few external passive components provide all of the functions needed to satisfy HART physical layer requirements including modulation, demodulation, receive filtering, carrier detect and transmit-signal shaping. The A5191HRTL is pincompatible with the SYM20C15.
