The SGM8140 is a PIR sensor and vibration sensor analog front end which consists of 2 independent building block circuits. One is a dual rail-to-rail input and output operational amplifier, and the other is an ultra-low power comparator. Both the operational amplifier and the comparator have been specifically designed to operate over a wide range of voltages from 1.4V to 5.5V. The SGM8140 only consumes 1.1μA working current, so it is ideal for use in a variety of battery-powered applications.

The operational amplifier is unity-gain stable and features a 5kHz gain-bandwidth product. It is suitable for low frequency systems in the case of monitoring battery current and conditioning sensor signal.

The comparator has a push-pull output, which drive resistive or capacitive with absolute lowest power consumption.

The SGM8140 is available in a Green TQFN-4×4-16L package. It is specified for the -40 to +85 industrial temperature range.
