Overview
The AD824ARZ-14-3V-RL, produced by Analog Devices Inc., is a quad, FET-input, single-supply operational amplifier. This device is part of the AD824 series and is known for its low power consumption, rail-to-rail output swing, and extremely low input bias current. The AD824 is fabricated on a complementary bipolar process, making it suitable for a wide range of low-voltage applications where low input current is crucial.
The amplifier operates from a single supply of 3 V to 30 V or dual supplies up to ±15 V, and it features a unique input stage that prevents phase inversion or latch-up even when the input voltage extends beyond the supply rails. This makes the AD824 ideal for use in battery-powered medical equipment, photo diode preamplifiers, and high impedance transducer amplifiers.
