Application Notes

Adjustable Analog Filter

Dialog Semiconductor

There are a variety of applications where signals from different sources (for example, sensors) are sensed with one ADC. Such systems require an analog multiplexer with analog filters for each channel, because each signal source may have its own set of filter requirements (for example, different cutoff frequencies). An alternative space-efficient and cost-efficient solution is to use one tunable analog filter for all channels. The SLG47004 IC solves this task perfectly.

Tamper Detector

Dialog Semiconductor

Tamper detection is a function widely used within critical infrastructure systems such as power meters, water meters, security and fire panels, and any other products where a trigger input needs to be detected and the event recorded in non-volatile memory (Flash memory). The SLG46811 GreenPAK mixed-signal IC is ideally suited for this tamper-detection role when paired with the AT45DB161E Flash memory for recording the event.
