Key Document


TIDA-00376 uses Texas Instrument’s industrial piezo driver, flash LED driver, and the ultra-low-power FRAM microcontroller (MCU) to demonstrate the implementation of both audible and visual notification subsystems, primarily intended for fire alert end-equipment systems. The TI Design demonstrates multiple alert tone frequency outputs through a single piezo transducer, as well as a low input current, high light output LED strobe.

  • Meets NFPA 72 Code requirements for audible and visual notification devices
  • 86.5 dBA @ 3m (520 Hz Square Wave)
  • 80.5 dBA @ 3m (2.84 kHz Sine Wave)
  • 77.5 dBA @ 3m (Pre-Recorded Speech)
  • 300 candela @ 3m (Flash Mode)
  • 1.44 W power consumption (Audible & Visual Notification)
