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.

Functional Description (cont’d)
An RC combination is needed to generate the fundamental frequency (pin ROSC , COSC). The volume
can be adjusted with another resistor (pin L). The loudspeaker must be connected directly between
the output Q and the power supply VS . The current-sink principle combined with an integrated
thermal shutdown (with hysteresis) makes the IC overload-protected and shortcircuit-protected.
There are two trigger pins (E1, E2) for setting single-tone, dual-tone or triple-tone mode.
