The DACx3701 are also used to generate continuous alarm tones for medical devices. Use a suitable analog mixer, audio amplifier, and a speaker to generate low, medium, or high priority alarm tones. See the Application and Implementation section for more details. The DACx3701 allow tunability and configurability to support different alarm generation. Using this approach, configurable medical alarm tones can be generated with a simple circuit, and with no need for runtime software. The GPI pin can be used for trigerring an alarm directly without using the I²C interface. This feature helps when the processor fails or the software crashes. This feature is also helpful when there is a power failure and the alarm circuit is driven by a battery or a super capacitor.
