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 = 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 /

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.

Circuit Description

Trigger

Positive pulses on inputs E1 and/or E2 trigger the IC. The hold feedback in the logic has a delay of several milliseconds. After this delay has elapsed, the tone sequence is started. This prevents parasitic spikes from producing any effect on the trigger pins.
