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-tonemode 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.
