Datasheet Details

Part number:

SAE800G

Manufacturer:

Siemens Semiconductor Group

File Size:

0.96 MB

Description:

Programmable Single-/Dual-/Triple- Tone Gong

Features

* q q q q q q q q q Supply voltage range 2.8 V to 18 V Few external components (no electrolytic capacitor) 1 tone, 2 tones, 3 tones programmable Loudness control Typical standby current 1 µA Constant current output stage (no oscillation) High-efficiency power stage Short-circuit protection Thermal sh

Applications

* Resistor RL on pin L sets the output voltage swing. This assumes that the resistive component of the loudspeaker impedance RQ responds similarly as the resistance RL. The output amplitude of the current II reaches the maximum IImax ≅ 3 x VL / RL at a time t of 2.33 s (only 3 tone mode), so RL has t
