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.

Logic
The logic unit contains the complete sequence control. The oscillator produces the power-on reset
and the clock frequency. Single-tone, dual-tone or triple-tone operation is programmed on inputs
E1 and E2. The 4-bit digital/analog converters are driven in parallel. In the event of oscillator
disturbance, and after the sequence, the dominant stop output is set. By applying current to pin L,
the sequence can be shortened by a factor of 30 for test purposes.
The following figure shows the envelope of the triple-tone sequence:

*) Note that IQ = f (IL) varies between 0 and K IL during tone sequence. Thereby the maximum of the power
dissipation during the tone sequence is the maximum of Pv (in diagram) between IL = 0 and chosen IL = VL/RL.
