The AD8612ARUZ is an ultra-fast low-voltage, single-supply amplifier comparator manufactured by Analog Devices. It is a 14-lead, small outline plastic package. It features a fixed 4-ns propagation delay time and a low voltage-drop supply, allowing for a wide supply range of 2 V to 16 V. The comparator also features an internal hysteresis voltage to reduce output oscillation through noise and excess slew rate. The AD8612ARUZ can be used in applications such as vehicle safety, motor control, audio, voice and speech recognition, amplifiers, security systems, and e-signatures.
