Design An Alarm System Using Voltage Detector Op Amp

Design An Alarm System Using Voltage Detector Op Amp. • gain bandwidth product • slew rate (sr) the minimum gain bandwidth product requirement can be estimated in equation 2. The design of the fire alarm circuit with siren sound is very simple.

LabIV Op amp SignalConditioning Circuit for 3Wire RTD from sites.google.com

A smoke detector is a device that detects smoke, ty pically as an indicator of fire. These circuits should also be simulated on pspice. A high speed op amp has a much greater slew rate, so its able to output voltage at a greater rate than a regular op amp.
