Specialized

HART modemFOUNDATION FieldbusPROFIBUS PAUARTindustrial communicationVQFN-24

DAC8740HRGET is a UART-interface industrial modem for HART, FOUNDATION Fieldbus H1 and PROFIBUS PA designs in a 24-pin 4 mm × 4 mm VQFN package.

Best for

  • UART-based industrial field transmitters
  • HART-enabled 4 mA to 20 mA transmitter designs
  • FOUNDATION Fieldbus or PROFIBUS PA interface designs

Avoid if

  • An SPI host interface is required
  • The system cannot support the required analog modem coupling and filtering network
  • Operating ambient temperature exceeds +105 °C

Check before use

  • Verify HART or FF/PA hardware clock strap settings
  • Verify AVDD is 2.7 V to 5.5 V and IOVDD is 1.71 V to 5.5 V
  • Use the required external capacitors for MOD_OUT, REG_CAP, reference and filter configuration
