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
f
0
= 13.2 kHz for example, the IC will issue in
triple-tone-
mode
the minor and major third e
2
– C sharp – a, corresponding to 660 Hz – 550 Hz – 440 Hz, in
dual-tone-mode
the minor third e
2
– C sharp, and in
single-tone-mode
the tone e
2
(derived from
the fundamental frequency

=
f
0
/ 20,
f
2
=

0
/ 24,
f

/ 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.
