SAE800 Programmable Single-/Dual-/Triple- Tone Gong

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 .
