Analog Devices OP490 Manuals

The document provides an overview of OP490, including working principle, features and characteristics

The OP490 is a low voltage, micropower, quad operational amplifier with features including single/dual-supply operation, input and output voltage ranges including ground, low supply current, high output drive, low offset voltage, and high open-loop gain.

This datasheet introduces the features and characteristics of OP490 low voltage micropower quad operational amplifier. The amplifier supports single or dual supply operation, input voltage range includes the negative rail, single supply operation supports input signal down to ground, output swing also includes ground, enabling “zero-in, zero-out” operation. The amplifier draws less than 20 mA of quiescent supply current per amplifier, but each amplifier is able to deliver over 5 mA of output current, with extremely low power consumption and high output drive capability.
