Product details

Four J-FET amplifiers in a 14-SOIC — 560 µA per channel, rail-to-rail output

The AD824ARZ-14-REEL from Analog Devices packs four J-FET input amplifiers into a single 14-SOIC package, each channel drawing 560 µA of supply current.

The 3 V minimum supply span means this quad op-amp can run directly off a single lithium cell or a 3.3 V regulated rail, while the 30 V maximum covers 24 V industrial buses without an extra regulator.

Input bias and offset — J-FET advantage for high-impedance sources

The J-FET input stage delivers a typical input bias current of 4 pA and an input offset voltage of 500 µV. That low bias current is the main reason to pick this part over a bipolar-input quad op-amp: it won't load down a high-impedance sensor output (pH probe, photodiode, piezoelectric accelerometer) or force you to add a buffer stage.

Frequently asked questions

Does AD824ARZ-14-REEL have rail-to-rail output?

Yes, the output type is rail-to-rail, meaning the output voltage can swing to within millivolts of both supply rails. The input common-mode range, however, is not rail-to-rail — it stops about 1.1 V below the positive rail, so high-side sensing at low supply voltages needs a different topology.

What is the slew rate of AD824ARZ-14-REEL?

The slew rate is 2 V/µs, paired with a 2 MHz gain-bandwidth product. This combination is adequate for audio-band signals and slow-slew sensor outputs up to a few hundred kHz, but it will limit large-signal fidelity above roughly 100 kHz peak-to-peak swing.
