Overview
The TLV3012, specifically the TLV3012AIDCKRG4, is a low-power, push-pull output comparator from Texas Instruments. This device is part of the TLV3011 and TLV3012 family, which includes the 'B' versions (TLV3011B and TLV3012B) that offer additional features such as power-on-reset, fail-safe inputs, and built-in hysteresis. The TLV3012 is designed for applications requiring low quiescent current and a wide input common-mode range that extends 200 mV beyond the supply rails.
The device features an integrated 1.242 V voltage reference with low temperature drift and high stability, making it suitable for a variety of precision analog circuits. It operates over a supply voltage range of 1.8 V to 5.5 V and is available in compact SOT23-6 and SC-70 packages, making it ideal for space-conservative designs.
