TLC2943IDB TI Analog Comparator | 38-SSOP | 4.5V-16V, 1.5μA

Product Overview

The TLC2943IDB from Texas Instruments is a quad-channel, low-power, precision voltage comparator in a 38-pin SSOP package. It operates from a single supply of 4.5V to 16V or dual supplies of ±2.25V to ±8V, with a typical supply current of only 1.5μA per channel. The device features open-drain outputs, making it suitable for wired-OR applications. With an input offset voltage of 5mV max and a response time of 1.3μs, it is ideal for battery-powered systems and portable equipment.
