AFE881H1RRUR

Analog Front End (AFE)

16-bit DACHART modem12-bit diagnostic ADCLoop-powered transmitterUQFN

AFE881H1RRUR is a 16-bit loop-transmitter AFE combining a voltage DAC, HART modem, diagnostic ADC, precision reference, and fault monitoring.

Best for

  • 2-wire 4-mA to 20-mA loop-powered transmitters
  • HART-enabled process sensors
  • Low-power industrial analog output with device diagnostics

Avoid if

  • The design needs a standalone current-output DAC without an external voltage-to-current stage
  • The required supply or output range is outside the documented PVDD configurations

Check before use

  • PVDD/VDD operating configuration and decoupling
  • DAC range, clear code, alarm action, and output headroom
  • SPI CRC or UART break-mode configuration
  • UQFN thermal pad and 0.5-mm pitch PCB layout
