TL331KDBVR TI Comparator | SOT-23-5 | Single, Open-Collector Output

Product Overview

The TL331KDBVR is a single-channel, low-power voltage comparator from Texas Instruments (TI), housed in a compact SOT-23-5 package. It is designed for applications requiring precision voltage comparison with minimal power consumption. The device features an open-collector output stage, enabling direct interfacing with various logic families and loads. With a wide supply voltage range of 2 V to 36 V (or ±1 V to ±18 V for dual supplies), the TL331KDBVR offers flexibility for both single and dual supply operations. Its low input offset voltage (typically 2 mV) and low input bias current (typically 25 nA) make it suitable for high-accuracy sensing and monitoring tasks.
