TIDA-00376
Piezo Speaker Strobe Notification Reference Design
TIDA-00376
Overview
TIDA-00376 uses our 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. This reference design demonstrates multiple alert-tone frequency outputs through a single piezo transducer, as well as a low-input current and high light-output LED strobe.
Features
- Meets NFPA 72 code requirements for audible and visual notification devices
- 86.5 dBA @ 3 m (520-Hz square wave)
- 80.5 dBA @ 3 m (2.84-kHz sine wave)
- 77.5 dBA @ 3 m (pre-recorded speech)
- 300 candela @ 3 m (flash mode)
- 1.44-W power consumption (audible and visual notification)
