Overview
The AD824ARZ-14, produced by Analog Devices Inc., is a quad, FET-input, single-supply operational amplifier featuring rail-to-rail outputs. This device is fabricated on Analog Devices' complementary bipolar process and is designed for low voltage applications where low input current is crucial. The AD824ARZ-14 operates from a single supply of 3 V to 30 V and can also function with dual supplies up to ±15 V. Its unique input stage allows the input voltage to extend beyond the supply rails without phase inversion or latch-up, making it highly versatile for various applications.
