Features & Applications

The A5191HRTLG-XTD is a single-chip, CMOS modem for use in highway addressable remote transducer (HART) field instruments and masters with data rate of upto 1200 bps.

The modem with 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.

Features:

  • Single−chip, Half−duplex 1200 Bits per Second FSK Modem
  • Bell 202 Shift Frequencies of 1200 Hz and 2200 Hz
  • 3.0 V − 5.5 V Power Supply
  • Transmit−signal Wave Shaping
  • Receive Band−pass Filter
  • Low Power: Optimal for Intrinsically Safe Applications
  • Compatible with 3.3 V or 5 V Microcontroller
  • Internal Oscillator Requires 460.8 kHz Crystal or Ceramic Resonator
  • Meets HART Physical Layer Requirements
  • Industrial Temperature Range of −40°C to +85°C
  • Available in 28−pin PLCC, 32−pin QFN and 32−pin LQFP Packages
  • These are Pb−Free Devices

Applications:

  • HART Multiplexers
  • HART Modem Interfaces
  • 4 − 20 mA Loop Powered Transmitters
