The document provides an overview of OP490, including working principle, features and characteristics
The OP490 quad operational amplifier from Analog Devices operates from a single supply of 1.6 V to 36 V or dual supplies of +0.8 V to +18 V. It features true single‑supply operation with input and output ranges that include ground, a low quiescent current of less than 20 µA per amplifier, and the ability to source over 5 mA of output current.
The device offers low offset voltage (0.5 mV typical), high open‑loop gain (≥700 k), excellent PSRR (5.6 V/V), and a gain‑bandwidth product of 20 kHz. It is supplied in 14‑lead DIP, 14‑lead plastic DIP, and 16‑lead SOIC packages and is suited for battery‑powered and solar‑powered applications such as portable instruments and remote sensors.
| Supply Voltage Range | 1.6 V to 36 V (single) or +0.8 V to +18 V (dual) |
|---|---|
| Maximum Output Current | ≥5 mA per amplifier |
The OP490 can run from a single supply of 1.6 V to 36 V or from dual supplies of +0.8 V to +18 V.
Each amplifier can deliver at least 5 mA of output current to a load.
