1.1 µA provides for extremely long battery service life:
2 operation amplifiers and 1 comparator in a space-saving housing
Have you ever been suddenly woken at night by smoke or fire alarms? Lucky that it was "just" the battery!
The analogue specialist SG MICRO offers a particularly power-saving analogue front end (AFE) specially for vibration and presence sensors.
The SGM8140, with its operating current of 1.1 µA (Vs = 5 V), provides extremely long battery service life for presence sensors, fire and smoke alarms and for temperature measuring, for example.
The input voltage is supported in a flexible manner using the bandwidth of 1.4 to 5.5 V.
2 OpAmps and 1 comparator: The SGM8140 combines three components in a space-saving housing. The AFE module facilitates Dual Rail-to-Rail (Input and Output).
The incorporated comparator supports a Push-Pull Output Stage.
It permits the control of capacitive and inductive loads with absolutely minimal energy consumption.
The SGM8140 is certified for a temperature range of -40 °C to 85 °C and is available in the TQFN-4×4-16L housing produced using "green" methods.
We would be pleased to send you some samples for testing and approval - just send us an email with the reference "SGM8140 Analogue Front End", together with your address and contact details.
