Overview
The TLV3492AIDCNT from Texas Instruments is a part of the TLV349x family of push-pull output comparators. This component is designed for low-power, high-speed applications and is particularly suited for battery-powered and space-constrained designs. It operates on a supply voltage range of 1.8 V to 5.5 V and features a very low supply current of typically 0.8 µA, making it ideal for ultra-low power systems. The comparator has a fast response time of 6 µs and includes input overvoltage protection and rail-to-rail input and output capabilities.
