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.
The SAE 800 is a programmable gong IC that can generate a single tone, two tones, or three tones over a wide supply voltage range. It features loudness control, low standby current, constant‑current output, short‑circuit protection, and thermal shutdown, making it suitable for chime and alarm applications.
The document lists detailed pin definitions, functional block diagrams, application circuit examples, absolute maximum ratings, operating voltage ranges, and package dimensions, allowing designers to integrate the device into their circuits with confidence.
| Supply voltage (operating) | 2.8 V – 18 V |
|---|---|
| Typical standby current | 1 µA |
| Maximum output current | 750 mA |
| Junction temperature (max) | 150 °C |
The device operates from 2.8 V to 18 V.
It can be programmed for single‑tone, dual‑tone, or triple‑tone operation.
The typical standby current is about 1 µA.
