Functional Description
The SAE 800 is a single-tone, dual-tone or triple-tone gong IC designed for a very wide supply
voltage range. If the oscillator is set to f₀ = 13.2 kHz for example, the IC will issue in triple-tone-
mode the minor and major third e² – C sharp – a, corresponding to 660 Hz – 550 Hz – 440 Hz, in
dual-tone-mode the minor third e² – C sharp, and in single-tone-mode the tone e² (derived from
the fundamental frequency f₀ ; f₁ = f₀ / 20, f₂ = f₀ / 24, f₃ = f₀ / 30).
When it is not triggered, the IC is in a standby state and only draws a few µA. It comes in a compact
P-DIP-8-1 or P-DSO-8-1 (SMD) package and only requires a few external components.
