The SGM8140 by SG Micro Corp is a versatile analog front end (AFE) designed for low-power applications. It integrates two independent building blocks: a dual rail-to-rail input/output operational amplifier and an ultra-low power comparator.
This device operates over a wide supply voltage range of 1.4V to 5.5V, consuming only 1.1μA of working current, making it suitable for battery-powered systems. The operational amplifier offers a 5kHz gain-bandwidth product and is unity-gain stable, ideal for low-frequency signal conditioning and battery current monitoring. The comparator features a push-pull output with a propagation delay of 6μs and a current drive of 19mA.
The SGM8140 is available in a Green TQFN-4x4-16L package and is specified for an industrial temperature range of -40℃ to +85℃. Its applications include toll booth tags, wearable products, vibration detectors, and alarm circuits.
